2016-12-27ARM: omap2+: am437x: rollback to use omap3_gptimer_timer_init()Grygorii Strashko2-5/+6
The commit 55ee7017ee31 ("arm: omap2: board-generic: use omap4_local_timer_init for AM437x") unintentionally changes the clocksource devices for AM437x from OMAP GP Timer to SyncTimer32K. Unfortunately, the SyncTimer32K is starving from frequency deviation as mentioned in commit 5b5c01359152 ("ARM: OMAP2+: AM43x: Use gptimer as clocksource") and, as reported by Franklin [1], even its monotonic nature is under question (most probably there is a HW issue, but it's still under investigation). Taking into account above facts It's reasonable to rollback to the use of omap3_gptimer_timer_init().

Legacy board files in mach-omap2 used the helper functions board_{nor,nand,onenand}_init() to initialize the flash devices attached to the GPMC. With Device Tree booting the initialization is handled by the GPMC driver gpmc_probe_*_child() functions so this code is not needed anymore now that OMAP2+ is DT-only.

When connecting an ethernet chip to the GPMC, such as smc91x or smsc911x, a GPIO has to be requested to be used as an IRQ and also the IO memory for a GPMC chip-select. When booting with DT the chip-select allocation is handled in a generic manner in the GPMC driver and the GPIO to IRQ mapping is made by the DT core so this code is not needed anymore now that mach-omap2 related boards are DT-only.

2016-11-10ARM: OMAP: DRA7xx: Make L4SEC clock domain SWSUP onlyJoel Fernandes1-1/+1
Using HWSUP for l4sec clock domain is causing warnings in HWMOD code for DRA7. Based on some observations, once the clock domain goes into an IDLE state (because of no activity etc), the IDLEST for the module goes to '0x2' value which means Interface IDLE condition. So far so go, however once the MODULEMODE is set to disabled for the particular IP, the IDLEST for the module should go to '0x3', per the HW AUTO IDLE protocol. However this is not observed and there is no reason per the protocl for the transition to not happen. This could potentially be a bug in the HW AUTO state-machine. Work around for this is to use SWSUP only for the particular clockdomain. With this all the transitions of IDLEST happen correctly and warnings don't occur.

2016-11-08ARM: OMAP5: Add basic cpuidle MPU CSWR supportSantosh Shilimkar2-2/+80
Add OMAP5 CPUIDLE support. This patch adds MPUSS low power states in cpuidle. C1 - CPU0 WFI + CPU1 WFI + MPU ON C2 - CPU0 RET + CPU1 RET + MPU CSWR Modified from TI kernel tree commit 605967fd2205 ("ARM: DRA7: PM: cpuidle MPU CSWR support") except enable cpuidle for omap5 instead of dra7. According to Nishanth Menon <nm@ti.com>, cpuidle on dra7 is not supported properly in the hardware so we don't want to enable it. However, for omap5 this adds some nice power savings. Note that the TI 3.8 based tree has other cpuidle states that we may be able to enable later on. On omap5-uevm, the power consumption eventually settles down to about 920mW with ehci-omap and ohci-omap3 unloaded compared to about 1.7W without these patches. Note that it seems to take few minutes after booting for the idle power to go down to 920mW from 1.3W, no idea so far what might be causing that.
