[PATCH] staging: fbtft replaced udelay with usleep_range
by Mayank Suman 05 Feb '21

05 Feb '21

According to Documentation/timers/timers-howto.rst, usleep_range is preffered over udelay for >=10us delay.

[PATCH v3 0/5] amba: minor fix and various cleanups
by Uwe Kleine-König 05 Feb '21

05 Feb '21

From: Uwe Kleine-König <u.kleine-koenig.org(a)pengutronix.de Hello, Changes since v2 sent with Message-Id: 20201124133139.3072124-1-uwe(a)kleine-koenig.org: - Rebase to v5.11-rc1 (which resulted in a few conflicts in drivers/hwtracing). - Add various Acks. - Send to more maintainers directly (which I think is one of the reasons why there are so few Acks). For my taste patch 4 needs some more acks (drivers/char/hw_random, drivers/dma, drivers/gpu/drm/pl111, drivers/i2c, drivers/mmc, drivers/vfio, drivers/watchdog and sound/arm have no maintainer feedback yet). My suggestion is to let this series go in via Russell King (who cares for amba). Once enough Acks are there I can also provide a tag for merging into different trees. Just tell me if you prefer this solution. Would be great if this could make it for v5.12, but I'm aware it's already late in the v5.11 cycle so it might have to wait for v5.13.
