2013-04-04video: mxsfb: remove mxsfb_platform_dataShawn Guo2-66/+17
None of mxsfb users uses mxsfb_platform_data now. Let's remove it from mxsfb driver. As the result, include/linux/mxsfb.h gets deleted with a few macros moved into mxsfb.c. Along with the change, the typo "FAILING" in macro name is fixed to be "FALLING". Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-04ARM: mxs: move display timing configurations into device treeShawn Guo7-158/+150
Move display timing configurations into device tree, so that the auxdata for mxsfb driver can be killed. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-04video: mxsfb: get display timings from device treeShawn Guo3-12/+146
Use videomode helpers to get display timings and configurations from device tree when platform_data is absent. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-04video: mxsfb: remove dotclk_delay from platform_dataShawn Guo2-2/+0
There is no in-tree mxsfb users using mxsfb_platform_data dotclk_delay. Let's remove it from mxsfb_platform_data to ease full device tree adoption of mxsfb driver. If later we have platform/board need to configure this parameter, we can add it into device tree bindings. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-04video: mxsfb: remove fb_phys/fb_size from platform_dataShawn Guo2-41/+7
There is no in-tree users of mxsfb_platform_data fb_phys/fb_size. With CMA support in the kernel, there is no real need for platform to reserve memory and pass address and size into driver via platform_data. So let's remove fb_phys/fb_size from mxsfb_platform_data to ease full device tree adoption. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-04video: mxsfb: use devm_* managed functionsShawn Guo1-34/+16
Use devm_* managed functions to make code a little cleaner. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-04ARM: mxs: remove unneeded enet_out clk initializationShawn Guo1-12/+0
With fec driver taking care of enet_out clk, most of board setup do not need to enable enet_out clk. So remove them. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-04ARM: dts: mxs: add enet_out clock to devicetreeWolfram Sang2-2/+4
Put the clock to the devicetree, so the driver can take care of it later. Then, we don't have to do the enabling as a workaround in board init. Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> [shawn.guo: add enet_out into imx28.dtsi and overwrite it for m28evk] Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-04net: freescale: fec: add support for optional enet_out clkWolfram Sang2-0/+11
Some MX28 boards need the internal enet_out clock to be enabled. So, do this in the driver iff the clock was referenced via devicetree. Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: David S. Miller <davem@davemloft.net>
2013-04-04net: fec: handle optional clk_ptp more gracefullyShawn Guo1-5/+3
When the optional clk_ptp is absent, we can just set it to NULL, and clk API will just handle it gracefully. It saves us from checking clk_ptp whenever calling into clk API. Also since clk_ptp is optional, the "ret" variable shouldn't be set in case that the clock is absent. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: David S. Miller <davem@davemloft.net>

2013-04-01ARM: mxs: remove unused headersShawn Guo5-533/+27
Most of the stuff in the headers are used nowhere now. Move a few things that are useful for mach-mxs.c into there and remove the headers. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: merge imx23 and imx28 into one machine_descShawn Guo1-30/+13
Most of the function hooks are same between imx23 and imx28 machine_desc, so merge them into one. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: remove common.hShawn Guo3-21/+17
All three remaining functions declared in common.h are implemented by clock driver. Create header include/linux/clk/mxs.h to contain them and remove common.h. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: move mxs_get_ocotp() into mach-mxs.cShawn Guo4-105/+76
All the users of mxs_get_ocotp() are in mach-mxs.c. Move the function into mach-mxs.c, make it a static function, and then remove ocotp.c. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: remove mm.cShawn Guo3-55/+1
The static mapping is used nowhere now. Hence mm.c can be removed completely. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: use debug_ll_io_init for low-level debugShawn Guo2-8/+6
The only user of the static mapping done in mx23_map_io and mx28_map_io is low-level debug now. Use debug_ll_io_init() instead, so that the static mapping is used nowhere and can be removed completely later. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: get ocotp base address from device treeShawn Guo3-1/+10
Instead of using the static definitions, get ocotp base address from device tree with mapping. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: remove system.cShawn Guo4-140/+38
There is no user of function mxs_reset_block() now. Let's move mxs_restart() into mach-mxs.c as a static function and remove system.c completely. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: get reset address from device treeShawn Guo3-21/+19
Instead of using static address definition, get reset address from device tree with mapping, so that core_initcall mxs_arch_reset_init() can be killed. The "rtc" clock code in mxs_arch_reset_init() seems to be zombie, since there is no clk lookup defined in clock driver at all. Remove it together. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: remove empty hardware.hShawn Guo2-24/+0
The hardware.h is an empty header and used nowhere now. Remmove it. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ASoC: mxs-saif: remove mach header inclusionShawn Guo1-2/+3
The header <mach/hardware.h> is not needed at all, and <mach/mxs.h> is needed only for macros MXS_SET_ADDR and MXS_CLR_ADDR. Define the macros and remove the mach header inclusions. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-04-01iio: mxs-lradc: remove unneeded mach header inclusionShawn Guo1-3/+0

2013-04-01rtc: stmp3xxx: use stmp_reset_block() insteadShawn Guo1-4/+2
The function stmp_reset_block() provides the exactly same functionality as mxs_reset_block(). So use stmp_reset_block() instead, so that <mach/common.h> inclusion can be removed.

2013-04-01clk: mxs: remove the use of mach level IO accessorShawn Guo2-13/+11
It removes the use of mach level IO accessor __mxs_setl/clrl, and hence removes mach header inclusion from clock driver. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Mike Turquette <mturquette@linaro.org>
2013-04-01clk: mxs: get base address from device treeShawn Guo4-16/+37
Instead of using the static definitions, get clkctrl and digctl base addresses with mapping from device tree. Use macro on variable is not nice, but it's done here to save huge pointless diff stat. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Mike Turquette <mturquette@linaro.org>
2013-04-01ARM: mxs: remove unneeded mach-types.h inclusionShawn Guo1-1/+0

2013-04-01ARM: mxs: move icoll driver into drivers/irqchipShawn Guo6-16/+23
Move icoll.c into drivers/irqchip as irq-mxs.c, and along with the renaming, change the driver to use IRQCHIP_DECLARE. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: call stmp_reset_block() in icollShawn Guo1-2/+2
Call stmp_reset_block() rather than mxs_reset_block(), so that <mach/common.h> inclusion can be removed from icoll driver. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: get icoll base address from device treeShawn Guo1-2/+5
Rather than using the static definition, it gets icoll base address with mapping from device tree. As the result, <mach/mxs.h> inclusion can be removed from the driver now. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: move timer driver into drivers/clocksourceShawn Guo3-1/+2
Move mxs timer driver into drivers/clocksource as mxs_timer.c. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: select STMP_DEVICE and use it for timer codeShawn Guo2-9/+9
Select STMP_DEVICE and in timer code replace mxs_reset_block() with stmp_reset_block(), use STMP_OFFSET_REG_SET/CLR to replace __mxs_setl/clrl. As the result, <mach/mxs.h> and <mach/common.h> includsion can be removed from timer.c now. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: remove cpu_is_mx23() call from timer codeShawn Guo1-1/+2
Remove cpu_is_mx23() call from timer code by using of_device_is_compatible() instead. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: get timrot base address from device treeShawn Guo1-1/+5
Instead of using static defines, it gets timrot base address with mapping from device tree. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: look up timrot clock from device treeShawn Guo5-4/+3
Change call clk_get_sys() to of_clk_get() to look up timrot clock from device tree, so that the clk_register_clkdev() call for timrot can be saved in clock driver. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-01ARM: mxs: use CLKSRC_OF helper to initialize timerShawn Guo6-15/+6
Select CLKSRC_OF and use clocksource_of_init() to initialize timer, so that the call to mxs_timer_init() in clock driver can be removed. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
