commit 618c8089 upstream. The maximum supported voltage for ldo_io# is 3.3V, but on cold boot the selector comes up at 0x1f, which maps to 3.8V. This was previously corrected by Allwinner's U-boot, which set all regulators on the PMICs to some pre-configured voltage. With recent progress in U-boot SPL support, this is no longer the case. In any case we should handle this quirk in the kernel driver as well. This invalid setting causes _regulator_get_voltage() to fail with -EINVAL which causes regulator registration to fail when constrains are used: [ 1.054181] vcc-pg: failed to get the current voltage(-22) [ 1.059670] axp20x-regulator axp20x-regulator.0: Failed to register ldo_io0 [ 1.069749] axp20x-regulator: probe of axp20x-regulator.0 failed with error -22 This commits makes the axp20x regulator driver accept the 0x1f register value, fixing this. The datasheet does not guarantee reliable operation above 3.3V, so on boards where this regulator is used the regulator-max-microvolt setting must be 3.3V or less. This is essentially the same as the commit f40d4896 ("regulator: axp20x: Fix axp22x ldo_io registration error on cold boot") for AXP22x PMICs.

commit c314c9f1 upstream. On some SoC there are no simple mapping of pins to bias register bits and a lookup table is needed. This logic is already implemented in some SoC specific drivers that could benefit from a generic implementation. Add helpers to deal with the lookup which later can be used by the SoC specific drivers. The logic used to lookup are different from the one it aims to replace, this is intentional. This new method reduces the memory consumption at the cost of increased CPU usage and fix a bug where a WARN() would incorrectly be triggered if the register offset is 0. Signed-off-by:

In commit a5ffbe0a ("rtlwifi: Fix scheduling while atomic bug") and commit a269913c ("rtlwifi: Rework rtl_lps_leave() and rtl_lps_enter() to use work queue"), an error was introduced in the power-save routines due to the fact that leaving PS was delayed by the use of a work queue. This problem is fixed by detecting if the enter or leave routines are in interrupt mode. If so, the workqueue is used to place the request. If in normal mode, the enter or leave routines are called directly. Fixes: a269913c ("rtlwifi: Rework rtl_lps_leave() and rtl_lps_enter() to use work queue") Reported-by:

commit 2c7d0602 upstream. commit 848496e5 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Wed Jul 13 16:32:03 2016 +0300 drm/i915: Wait up to 3ms for the pcu to ack the cdclk change request on SKL increased the timeout to match the spec, but we still see a timeout on at least one SKL. A CDCLK change request following the failed one will succeed nevertheless. I could reproduce this problem easily by running kms_pipe_crc_basic in a loop. In all failure cases _wait_for() was pre-empted for >3ms and so in the worst case - when the pre-emption happened right after calculating timeout__ in _wait_for() - we called skl_cdclk_wait_for_pcu_ready() only once which failed and so _wait_for() timed out. As opposed to this the spec says to keep retrying the request for at most a 3ms period. To fix this send the first request explicitly to guarantee that there is 3ms between the first and last request. Though this matches the spec, I noticed that in rare cases this can still time out if we sent only a few requests (in the worst case 2) _and_ PCODE is busy for some reason even after a previous request and a 3ms delay. To work around this retry the polling with pre-emption disabled to maximize the number of requests. Also increase the timeout to 10ms to account for interrupts that could reduce the number of requests. With this change I couldn't trigger the problem. v2: - Use 1ms poll period instead of 10us. (Chris) v3: - Poll with pre-emption disabled to increase the number of request attempts. (Ville, Chris) - Factor out a helper to poll, it's also needed by the next patch. v4: - Pass reply_mask, reply to skl_pcode_request(), instead of assuming the reply is generic. (Ville) v5: - List the request specific timeout values as code comment. (Ville) v6: - Try the poll first with preemption enabled. - Add code comment about first request being queued by PCODE. (Art) - Add timeout_base_ms argument. (Ville) v7: - Clarify code comment about first queued request.

commit 7243e0b2 upstream. The calculation of SPR and SPPR doesn't round correctly at several places which might result in baud rates that are too big. For example with tclk_hz = 250000001 and target rate 25000000 it determined a divider of 10 which is wrong. Instead of fixing all the corner cases replace the calculation by an algorithm without a loop which should even be quicker to execute apart from being correct.

commit f86a2c87 upstream. The commit 55ee7017 ("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 5b5c0135 ("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().

commit 9388093d upstream. Unlike clk_register_clkdev(), clk_hw_register_clkdev() doesn't check for passed error objects from a previous registration call. Hence the caller of clk_hw_register_*() has to check for errors before calling clk_hw_register_clkdev*(). Make clk_hw_register_clkdev() more similar to clk_register_clkdev() by adding this error check, removing the burden from callers that do mass registration.

So whenever that happens we must disable the frag0 optimization. This is usually done through the combination of gro_header_hard and gro_header_slow, however, the IPv6 extension header path did the pulling directly and would continue to use the GRO fast path incorrectly.
