2016-06-22ARM: OMAP4+: Prevent CPU1 related hang with kexecTony Lindgren
Kexec booted kernels on omap4 will hang early during the boot if the booted kernel is different version from the previous kernel. This is because the previous kernel may have configured low-power mode using CPU1_WAKEUP_NS_PA_ADDR. In that case it points to the previous kernel's omap4_secondary_startup(), and CPU1 can be in low power mode from the previous kernel. When the new kernel configures the CPU1 clockdomain, CPU1 can wake from low power state prematurely during omap44xx_clockdomains_init() running random code. Let's fix the issue by configuring CPU1_WAKEUP_NS_PA_ADDR before we call omap44xx_clockdomains_init(). Note that this is very early during the init, and we will do proper CPU1 reset during SMP init a bit later on in omap4_smp_prepare_cpus(). And we need to do this when SMP is not enabled as the previous kernel may have had it enabled.

2016-06-22ARM: OMAP4+: Initialize SAR RAM base early for proper CPU1 reset for kexecTony Lindgren
Prepare things for making kexec work on SMP omap variants by initializing SARM RAM base early. This allows us to configure CPU1 for kexec in case the previous kernel has put CPU1 in low power mode. Note that this should not prevent moving other SAR RAM code to live under drivers. However for kexec, we will need this very early.

2015-03-16ARM: OMAP4: remove dead kconfig option OMAP4_ERRATA_I688Stefan Hengelein
The Kconfig-Option OMAP4_ERRATA_I688 is never visible due to a contradiction in it's dependencies. The option requires ARCH_MULTIPLATFORM to be 'disabled'. However, an enclosing menu requires either ARCH_MULTI_V6 or ARCH_MULTI_V7 to be enabled. These options inherit a dependency from an enclosing menu, that requires ARCH_MULTIPLATFORM to be 'enabled'. This is a contradiction and made this option also unavailable for non-multiplatform configurations. Since there are no selects on OMAP4_ERRATA_I688, which would ignore dependencies, the code related to that option is dead and can be removed. This (logical) defect has been found with the undertaker tool.

2015-01-17ARM: OMAP: Work around hardcoded interruptsMarc Zyngier
Commit 9a1091ef0017 ("irqchip: gic: Support hierarchy irq domain") changed the GIC driver to use a non-legacy IRQ domain on DT platforms. This patch assumes that DT-driven systems are getting all of their interrupts from device tree. Turns out that OMAP has quite a few hidden gems, and still uses hardcoded interrupts despite having fairly complete DTs. This patch attempts to work around these by offering a translation method that can be called directly from the hwmod code, if present. The same hack is sprinkled over PRCM and TWL. It isn't pretty, but it seems to do the job without having to add more hacks to the interrupt controller code. Tested on OMAP4 (Panda-ES) and OMAP5 (UEVM5432).

2015-01-05ARM: omap5/dra7xx: Enable booting secondary CPU in HYP modeLennart Sorensen
If the boot loader enables HYP mode on the boot CPU, the secondary CPU also needs to call into the ROM to switch to HYP mode before booting. The firmwares on the omap5 and dra7xx unfortunately do not take care of this, so it has to be handled by the kernel. This patch is based on "[PATCH 2/2] ARM: OMAP5: Add HYP mode entry support for secondary CPUs" by Santosh Shilimkar <santosh.shilimkar@ti.com>, except this version does not require a compile time CONFIG to control if it should enable HYP mode or not, it simply does it based on the mode of the boot CPU, so it works whether the CPU boots in SVC or HYP mode, and should even work as a guest kernel inside kvm if qemu decides to support emulating the omap5 or dra7xx.

2014-06-17ARM: omap2: fix am43xx dependency on l2x0 cacheArnd Bergmann
Commit d941f86fad41b ("ARM: l2c: AM43x: add L2 cache support") enabled the L2 cache support for the am43xx SoC, but caused a build regression when the driver for that cache controller is disabled: arch/arm/mach-omap2/built-in.o: In function `am43xx_init_early': :(.init.text+0xb20): undefined reference to `omap_l2_cache_init' This did not happen for OMAP4, which has the same call, but enables the l2x0 driver unconditionally. We could do the same thing for am43xx, but it seems better to allow turning it off and make the code work in either case. This adds an inline wrapper for omap_l2_cache_init for the disabled case, and removes the 'select' from OMAP4 so it becomes a user visible option.

2014-03-19ARM: OMAP2+: DT 'compatible' tweak for displaysTomi Valkeinen
As there is no common panel framework in the kernel, we have OMAP specific panel drivers. However, the DT data should be generic. This brings the issue that some other platform could use the same panels, and would need to create a driver with the same 'compatible' string as the OMAP driver. In the long run, we have to get a common panel framework. For the time being, this patch solves the issue: At early boot time, we go through the DT nodes looking for the panels the kernel supports for OMAP. For each found node, the 'compatible' string is prepended with "omapdss,", i.e. "sony,acx565akm" becomes "omapdss,sony,acx565akm". The OMAP display drivers all have "omapdss," at the beginning of their compatible field. This allows us to have generic DT data, but OMAP specific display drivers.

2014-03-19ARM: OMAP2+: add omapdss_init_of()Tomi Valkeinen
The OMAP display architecture requires a bunch of platform devices which are not created via .dts (for now). We also need to pass a few function pointers and the DSS hardware version from the arch code to omapdss driver. This patch adds omapdss_init_of() function, called from board-generic at init time, which handles those tasks.

2013-12-08ARM: OMAP2+: Add support for legacy auxdata for twlTony Lindgren
As we currently need to support a mix of legacy platform data and device tree intialized data, let's make sure things keep working for the TWL GPIOs. Mostly the issue is caused by the fact that DSS does not yet have device tree bindings, so we need to rely on the TWL GPIO callback for setting up things like LCD backlight for some boards. As of_platform_populate() for the TWL GPIO is called by twl-core after the I2C bus has been initialized, we cannot pass the auxdata table from the board init code to twl-core like we used to with just legacy platform data. So let's use the omap_device bus hook to patch in the platform data for TWL GPIO until we have sorted out the issues with the TWL GPIOs and device tree bindings. The other option was be to initialize twl core using legacy platform data, which seems like a step backwards as we're moving to device tree only initialization. And we really don't want to add custom configuration functions to the TWL GPIO driver either for this. Signed-off-by: Tony Lindgren <tony@atomide.com>

AM335x, AM43xx, OMAP5 and DRA7 have missing late init hook. Introduce SoC specific hook with a call to OMAP2+ generic lateinit hook. This allows the generic late initializations such as cpufreq hooks to be active.
