mmc: core: Rework wp-gpio handling

2020-02-19T18:54:13Z

[ Upstream commit 9073d10b098973519044f5fcdc25586810b435da ] Use MMC_CAP2_RO_ACTIVE_HIGH flag as indicator if GPIO line is to be inverted compared to DT/platform-specified polarity. The flag is not used after init in GPIO mode anyway. No functional changes intended.

gpio: add gpiod_toggle_active_low()

2020-02-19T18:54:13Z

[ Upstream commit d3a5bcb4a17f1ad072484bb92c42519ff3aba6e1 ] Add possibility to toggle active-low flag of a gpio descriptor. This is useful for compatibility code, where defaults are inverted vs DT gpio flags or the active-low flag is taken from elsewhere.

ext4: choose hardlimit when softlimit is larger than hardlimit in ext4_statfs_project()

2020-02-19T18:54:13Z

[ Upstream commit 57c32ea42f8e802bda47010418e25043e0c9337f ] Setting softlimit larger than hardlimit seems meaningless for disk quota but currently it is allowed. In this case, there may be a bit of comfusion for users when they run df comamnd to directory which has project quota. For example, we set 20M softlimit and 10M hardlimit of block usage limit for project quota of test_dir(project id 123).

drm/i915/pmu: Correct the rc6 offset upon enabling

2020-02-19T18:54:12Z

commit 88a9c66d998b1d2dac412fcd458c5d17d70513c8 upstream. The rc6 residency starts ticking from 0 from BIOS POST, but the kernel starts measuring the time from its boot. If we start measuruing I915_PMU_RC6_RESIDENCY while the GT is idle, we start our sampling from 0 and then upon first activity (park/unpark) add in all the rc6 residency since boot. After the first park with the sampler engaged, the sleep/active counters are aligned. v2: With a wakeref to be sure Closes: https://gitlab.freedesktop.org/drm/intel/issues/973 Fixes: df6a42053513 ("drm/i915/pmu: Ensure monotonic rc6") Signed-off-by: Chris Wilson Cc: Tvrtko Ursulin Reviewed-by: Tvrtko Ursulin Link: https://patchwork.freedesktop.org/patch/msgid/20200114105648.2172026-1-chris@chris-wilson.co.uk (cherry picked from commit f4e9894b6952a2819937f363cd42e7cd7894a1e4) Signed-off-by: Jani Nikula Signed-off-by: Greg Kroah-Hartman

Revert "drm/sun4i: drv: Allow framebuffer modifiers in mode config"

2020-02-19T18:54:12Z

commit cf913e9683273f2640501094fa63a67e29f437b3 upstream. This reverts commit 9db9c0cf5895e4ddde2814360cae7bea9282edd2. Setting mode_config.allow_fb_modifiers manually is completely unnecessary. It is set automatically by drm_universal_plane_init() based on the fact if modifier list is provided or not. Even more, it breaks DE2 and DE3 as they don't support any modifiers beside linear. Modifiers aware applications can be confused by provided empty modifier list - at least linear modifier should be included, but it's not for DE2 and DE3.
