18:50:53 +0800 Subject: [ARM] pxa: make pxa2xx_spi driver use ssp_request()/ssp_free() 1. make pxa2xx_spi.c use ssp_request() and ssp_free() to get the common information of the designated SSP port. 2. remove those IRQ/memory request code, ssp_request() has done that for the driver 3. the SPI platform device is thus made psuedo, no resource (memory/IRQ) has to be defined, all will be retreived by ssp_request() 4. introduce ssp_get_clk_div() to handle controller difference in clock divisor setting 5. use clk_xxx() API for clock enable/disable, and clk_get_rate() to handle the different SSP clock frequency between different processors Signed-off-by: eric miao Signed-off-by: Russell King --- arch/arm/mach-pxa/lubbock.c | 17 ----- drivers/spi/Kconfig | 1 + drivers/spi/pxa2xx_spi.c | 138

First, the MFP configuration has to be set to enable which edges a specific pin will trigger a wakeup. The pin also has to be routed to a functional unit. Lastly, the functional unit must be enabled as a wakeup source in the appropriate AD*ER registers (AD2D0ER for standby resume.) This doesn't fit well with the IRQ wake scheme - we currently do a best effort conversion from IRQ numbers to functional unit wake enable bits. For instance, there's several USB client related enable bits but there's no corresponding IRQs to determine which you'd want.

Eg: PXA270 standby: "In standby mode, all clocks are disabled except those for the power manager and the RTC." PXA270 sleep: "In sleep mode, all clocks are disabled to the processor and to all peripherals except the RTC." PXA255 sleep: "In Sleep Mode, all processor and peripheral clocks are disabled, except the RTC." Therefore, it should be safe to leave the clock enable register alone prior to entering low power modes for these SoCs.

Since PXA27x requires at least MIN_OSCR_DELTA, this causes us to flag an error. tick_program_event() then increments the next event time by min_delta_ns. However, by the time we get back to programming the next event, the OSCR has incremented such that we fail again. We repeatedly retry, but the OSCR is too fast for us - we never catch up, so we never break out of the loop - resulting in us never apparantly resuming. Fix this by doubling min_delta_ns.

Russell King Date: Mon, 14 Jan 2008 22:30:10 +0000 Subject: [NET] smc91x: Make smc91x use IRQ resource trigger flags smc91x is shared between many different platforms. Each platform needs to specify the interrupt type, and in some cases the irq type depends on more than just the build configuration - it depends on runtime checks. Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide a way for these flags to be passed via the IRQ resource itself. Note that IRQF_TRIGGER_* constants are intentionally defined to correspond with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that the low bits of PCI iomem resources correspond with the BAR flag bits. Also provide a way to configure smc91x to read the IRQ flags from the resource. Once all platforms have been converted over (signified by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should be removed.

Its as generic as possible to support any kind of baseboard. Note: Neither the CPU module nor the pcm027.c implementation can work without a baseboard support. Baseboard support can be added by the PCM-990 or any custom variant. V2: After comments by Eric Miao: - Currently unsupported devices moved into separate patch - direct call of baseboard initialisation V3: After comments by Russell King - sort include files - setting RTC bit for power control removed - style problems fixed (discovered by checkpatch.pl) Signed-off-by: Juergen Beisert Signed-off-by: Russell King --- arch/arm/mach-pxa/Kconfig | 5 + arch/arm/mach-pxa/Makefile | 1 + arch/arm/mach-pxa/pcm027.c | 216 ++++++++++++++++++++++++++++++++++++++ include/asm-arm/arch-pxa/irqs.h | 10 +- include/asm-arm/arch-pxa/pcm027.h | 75 +++++++++++++ 5 files changed, 306 insertions(+), 1 deletion(-) create mode 100644 arch/arm/mach-pxa/pcm027.c create mode 100644 include/asm-arm/arch-pxa/pcm027.h (limited to 'arch') diff --git a/arch/arm/mach-pxa/Kconfig b/arch/arm/mach-pxa/Kconfig index c73da5e33067..958303c100b0 100644 --- a/arch/arm/mach-pxa/Kconfig +++ b/arch/arm/mach-pxa/Kconfig @@ -123,6 +123,11 @@ config MACH_MAGICIAN select PXA27x select IWMMXT +config MACH_PCM027 + bool "Phytec phyCORE-PXA270 CPU module (PCM-027)" + select PXA27x + select IWMMXT + endchoice if PXA_SHARPSL diff --git a/arch/arm/mach-pxa/Makefile b/arch/arm/mach-pxa/Makefile index 5e9aec57642d..61d301805c80 100644 --- a/arch/arm/mach-pxa/Makefile +++ b/arch/arm/mach-pxa/Makefile @@ -20,6 +20,7 @@ obj-$(CONFIG_PXA_SHARP_C7xx) += corgi.o corgi_ssp.o corgi_lcd.o sharpsl_pm.o cor obj-$(CONFIG_PXA_SHARP_Cxx00) += spitz.o corgi_ssp.o corgi_lcd.o sharpsl_pm.o spitz_pm.o obj-$(CONFIG_MACH_AKITA) += akita-ioexp.o obj-$(CONFIG_MACH_POODLE) += poodle.o corgi_ssp.o +obj-$(CONFIG_MACH_PCM027) += pcm027.o obj-$(CONFIG_MACH_TOSA) += tosa.o obj-$(CONFIG_MACH_EM_X270) += em-x270.o obj-$(CONFIG_MACH_MAGICIAN) += magician.o diff --git a/arch/arm/mach-pxa/pcm027.c b/arch/arm/mach-pxa/pcm027.c new file mode 100644 index 000000000000..540c3bba5f9a --- /dev/null +++ b/arch/arm/mach-pxa/pcm027.c @@ -0,0 +1,216 @@ +/* + * linux/arch/arm/mach-pxa/pcm027.c + * Support for the Phytec phyCORE-PXA270 CPU card (aka PCM-027). + * + * Refer + * http://www.phytec.com/products/sbc/ARM-XScale/phyCORE-XScale-PXA270.html + * for additional hardware info + * + * Author: Juergen Kilb + * Created: April 05, 2005 + * Copyright: Phytec Messtechnik GmbH + * e-Mail: armlinux@phytec.de + * + * based on Intel Mainstone Board + * + * Copyright 2007 Juergen Beisert @ Pengutronix (j.beisert@pengutronix.de) + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + */ + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include "generic.h" + +/* + * ABSTRACT: + * + * The PXA270 processor comes with a bunch of hardware on its silicon. + * Not all of this hardware can be used at the same time and not all + * is routed to module's connectors.

4747/1: pcm027: support for pcm990 baseboard for phyCORE-PXA270 This patch adds baseboard support for the phyCORE-PXA270 development kit (aka PCM-990). This example shows how to use some phyCORE-PXA270 CPU module features on a baseboard in a standard manner. It could be used as a starting point for custom baseboard development. V2: After comments by Eric Miao: - IRQ chained handler fixed - video/graphic support moved to separate patch - ifdef/endif hell reduced ;-) V3: After comments by Russell King - initialise the mmci platform data statically V4: After comments by Russell King - wrong return value in pcm990_mci_init() fixed Signed-off-by: Juergen Beisert Signed-off-by: Russell King --- arch/arm/mach-pxa/Kconfig | 9 + arch/arm/mach-pxa/Makefile | 1 + arch/arm/mach-pxa/pcm990-baseboard.c | 330 ++++++++++++++++++++++++++++ include/asm-arm/arch-pxa/pcm990_baseboard.h | 275 +++++++++++++++++++++++ 4 files changed, 615 insertions(+) create mode 100644 arch/arm/mach-pxa/pcm990-baseboard.c create mode 100644 include/asm-arm/arch-pxa/pcm990_baseboard.h (limited to 'arch') diff --git a/arch/arm/mach-pxa/Kconfig b/arch/arm/mach-pxa/Kconfig index 958303c100b0..e5b7063ed818 100644 --- a/arch/arm/mach-pxa/Kconfig +++ b/arch/arm/mach-pxa/Kconfig @@ -130,6 +130,15 @@ config MACH_PCM027 endchoice +choice + prompt "Used baseboard" + depends on MACH_PCM027 + +config MACH_PCM990_BASEBOARD + bool "PHYTEC PCM-990 development board" + +endchoice + if PXA_SHARPSL choice diff --git a/arch/arm/mach-pxa/Makefile b/arch/arm/mach-pxa/Makefile index 61d301805c80..1af56805b954 100644 --- a/arch/arm/mach-pxa/Makefile +++ b/arch/arm/mach-pxa/Makefile @@ -21,6 +21,7 @@ obj-$(CONFIG_PXA_SHARP_Cxx00) += spitz.o corgi_ssp.o corgi_lcd.o sharpsl_pm.o sp obj-$(CONFIG_MACH_AKITA) += akita-ioexp.o obj-$(CONFIG_MACH_POODLE) += poodle.o corgi_ssp.o obj-$(CONFIG_MACH_PCM027) += pcm027.o +obj-$(CONFIG_MACH_PCM990_BASEBOARD) += pcm990-baseboard.o obj-$(CONFIG_MACH_TOSA) += tosa.o obj-$(CONFIG_MACH_EM_X270) += em-x270.o obj-$(CONFIG_MACH_MAGICIAN) += magician.o diff --git a/arch/arm/mach-pxa/pcm990-baseboard.c b/arch/arm/mach-pxa/pcm990-baseboard.c new file mode 100644 index 000000000000..3dda16a20049 --- /dev/null +++ b/arch/arm/mach-pxa/pcm990-baseboard.c @@ -0,0 +1,330 @@ +/* + * arch/arm/mach-pxa/pcm990-baseboard.c + * Support for the Phytec phyCORE-PXA270 Development Platform (PCM-990). + * + * Refer + * http://www.phytec.com/products/rdk/ARM-XScale/phyCORE-XScale-PXA270.html + * for additional hardware info + * + * Author: Juergen Kilb + * Created: April 05, 2005 + * Copyright: Phytec Messtechnik GmbH + * e-Mail: armlinux@phytec.de + * + * based on Intel Mainstone Board + * + * Copyright 2007 Juergen Beisert @ Pengutronix (j.beisert@pengutronix.de) + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + */ + +#include +#include +#include +#include +#include +#include +#include +#include + +/* + * The PCM-990 development baseboard uses PCM-027's hardeware in the + * following way: + * + * - LCD support is in use + * - GPIO16 is output for back light on/off with PWM + * - GPIO58 ...

Fix spitz_get_hsync_len() to call get_hsync_invperiod so pxafb can be compiled as a module. The confusing variables which represent the inverse horizintal sync period are renamed to "invperiod" consistently. An incorrect comment in corgi_ts.c is also corrected.
