So, after some preparations, we can take the next step and improve resetting the SCC. Patch #1 is a fix requested by the BSP team to be more robust in case the firmware did something unexpected before. Patches #2 and #3 are cleanups made possible after patch #1. Patches have been tested on a Renesas Salvator-XS (R-Car M3-N) and a Renesas Lager (R-Car H2) board. A note to Shimoda-san: I did not forget that the BSP team also suggested to use the SRCR3 register for a reset in probe(). However, it appears there is more to discuss there. This is why I decided to send out this series first because we want to have it anyhow. I'll send the SRCR3 RFC-patch later this week. This series depends on the just sent out series "[RFC PATCH 0/4] mmc: renesas_sdhi: reset SCC only when available". A branch (with some more extras) can be found here: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/sdhi/tap_en_v2 All the best, Wolfram Wolfram Sang (3): mmc: renesas_sdhi: clear TAPEN when resetting, too mmc: renesas_sdhi: merge the SCC reset functions mmc: renesas_sdhi: remove superfluous SCLKEN drivers/mmc/host/renesas_sdhi_core.c | 19 +++++-------------- 1 file changed, 5 insertions(+), 14 deletions(-) -- 2.28.0
