[PATCH v9 01/22] pinctrl: tegra: Fix write barrier placement in pmx_writel

2019-08-16 Thread Sowjanya Komatineni
pmx_writel uses writel which inserts write barrier before the register write. This patch has fix to replace writel with writel_relaxed followed by a readback and memory barrier to ensure write operation is completed for successful pinctrl change. Acked-by: Thierry Reding Reviewed-by: Dmitry Osip
