From 33939403112791866da6b64875385fa1b7d9865a Mon Sep 17 00:00:00 2001 From: Doug Anderson Date: Wed, 20 May 2015 13:34:08 -0700 Subject: ARM: rockchip: restore dapswjdp after suspend In the commit (0ea001d ARM: rockchip: disable dapswjdp during suspend) we made the assumption that we didn't need to restore dapswjdp after suspend because "the MASKROM will enable it back". It turns out that's not a safe assumption. In some cases (pending interrupts) it's possible that the WFI might act as a no-op and the MaskROM will never run. Since we're changing the bit, we should restore it ourselves.

In one case we need to assert reset before turning power off. In ther other case we need to turn power on and the deassert reset.

The wait time is affected by many aspects (e.g: cpu frequency, bootrom frequency, sram frequency, bus speed, ...). Although the cpus other than cpu0 will write the sram, the speedy is no the same as cpu0, if the cpu0 early wake up, perhaps the other cpus can't startup. As we know, the cpu0 can wake up when the cpu1/2/3 write the 'sram+4/8' and send the sev. Anyway..... At the moment, 1ms delay will be happy work for cpu up/down scripts test.

Coherent DMA buffers in Linux always have a cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption. For Zynq, this fix avoids memory inconsistencies between Gigabit Ethernet controller (GEM) and CPU when DMA_CMA is disabled.

Most upstream devs boot STi platform via JTAG which abuses the boot process by setting the PC of secondary cores directly. As a consquence, booting STi platforms via u-boot results in only the primary core being brought up as the code to manage the holding pen is not upstream. This patch adds the necessary code to bring the secondary cores out of the holding pen. It uses the cpu-release-addr DT property to get the address of the holding pen from the bootloader.

It will be needed on Armada 38x to re-enable the coherency after exiting from suspend to RAM. This preparation simply moves the function further down in coherency.c so that it can use coherency_type(), and uses that function to only do the Armada XP specific work if we are on Armada XP.

However, this check is already done by mvebu_armada_xp_gp_pm_init(), and there is no need to duplicate the check: callers of mvebu_pm_init() should now what they are doing. This commit is done in preparation to the addition of suspend/resume support on Armada 38x.

Until now, the code supported only the Armada XP GP board, so all functions and symbols were named with armada_xp_gp. However, it turns out that the Armada 388 GP also uses the same 3 GPIOs protocol to talk to the PIC microcontroller that controls the power supply. Since we are going to re-use the same code with no change for Armada 38x, this commit renames the functions and symbols to use just "armada" instead of "armada_xp_gp". Better names can be found if one day other boards having a different protocol/mechanism are supported in the kernel.

However, in standby mode, the SoCs stay powered and it is possible to wake-up from any interrupt sources. Since when the users configures the enabled wake-up sources there is no way to know if the user will be doing suspend to RAM or standby, we just allow all wake-up sources to be enabled, and only warn when entering suspend to RAM The purpose of this patch is to inform the user that in suspend to ram mode, the wake-up sources won't be taken into consideration.

This leaves out the case when we don't switch to the 32kHz clock when only entering the shallow suspend mode where the logic keeps running. So, set the correct threshold after we have determined if we switch to the 32kHz clock or stay with the 24MHz one. Also set the oscillator- stabilization to 0 if it is kept running during suspend, as it of course does not need to stabilize then.
