Fixes for omaps for v5.11-rc cycle The recent changes to switch SoCs to boot with ti-sysc interconnect target module driver and genpd caused few regressions: - The omap_prm reset driver needs to clear any reset bits deasserted by the bootloader or kexec boot for the three reset bit cases. Otherwise we can have an oops with accelerators starting to boot with potentially unconfigured MMU for example - Custom kernel configs are not automatically selecting simple-pm-bus driver that we now need to probe interconnects so we need to select it always - We are not passing legacy platform data in auxdata with simple-pm-bus like we do for simple-bus. We need to pass auxdata to simple-pm-bus so it can pass it to of_platform_populate() Then recent RCU changes started causing splats for cpuidle44xx that now need RCU_NONIDLE added to the calls in several places And then we have few device specific fixes: - We need to remove legacy spi-cs-hig for gta04 display to work, and set the gpio to active low - Omap1 specific ohci-omap needs to call gpio_free() - Droid4 needs to use padconf interrupt for the slider as the edge gpio interrupts may be lost for deeper idle states * tag 'omap-for-v5.11/fixes-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: omap4-droid4: Fix lost keypad slide interrupts for droid4 drivers: bus: simple-pm-bus: Fix compatibility with simple-bus for auxdata ARM: OMAP2+: Fix booting for am335x after moving to simple-pm-bus ARM: OMAP2+: Fix suspcious RCU usage splats for omap_enter_idle_coupled ARM: dts; gta04: SPI panel chip select is active low soc: ti: omap-prm: Fix boot time errors for rst_map_012 bits 0 and 1 ARM: OMAP1: OSK: fix ohci-omap breakage DTS: ARM: gta04: remove legacy spi-cs-high to make display work again Link: https://lore.kernel.org/r/pull-1611818709-243493@atomide.com Signed-off-by: Arnd Bergmann

bus: arm-integrator-lm: Add of_node_put() before return statement

2021-01-15T16:53:05Z

Every iteration of for_each_available_child_of_node() decrements the reference count of the previous node, however when control is transferred from the middle of the loop, as in the case of a return or break or goto, there is no decrement thus ultimately resulting in a memory leak. Fix a potential memory leak in arm-integrator-lm.c by inserting of_node_put() before a return statement. Issue found with Coccinelle.

drivers: bus: simple-pm-bus: Fix compatibility with simple-bus for auxdata

2021-01-15T10:50:49Z

After converting am335x to probe devices with simple-pm-bus I noticed that we are not passing auxdata for of_platform_populate() like we do with simple-bus. While device tree using SoCs should no longer need platform data, there are still quite a few drivers that still need it as can be seen with git grep OF_DEV_AUXDATA. We want to have simple-pm-bus be usable as a replacement for simple-bus also for cases where OF_DEV_AUXDATA is still needed. Let's fix the issue by passing auxdata as platform data to simple-pm-bus. That way the SoCs needing this can pass the auxdata with OF_DEV_AUXDATA. And let's pass the auxdata for omaps to fix the issue for am335x. As an alternative solution, adding simple-pm-bus handling directly to drivers/of/platform.c was considered, but we would still need simple-pm-bus device driver. So passing auxdata as platform data seems like the simplest solution.

bus: fsl-mc: make sure MC firmware is up and running

2020-12-09T18:50:40Z

Some bootloaders might pause the MC firmware before starting the kernel to ensure that MC will not cause faults as soon as SMMU probes due to no configuration being in place for the firmware. Make sure that MC is resumed at probe time as its SMMU setup should be done by now. Also included, a comment fix on how PL and BMT bits are packed in the StreamID.
