[PATCH v4 0/4] mmc: renesas_sdhi: add eMMC HS400 mode support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

this patch-set provides SDHI driver support for eMMC HS400.

Based on mmc-v4.17-2

Dependencies for applying these patches:
* none

Dependencies to test eMMC HS400:
* [PATCH] clk: renesas: rcar-gen3: Fix SD divider setting
* [PATCH v2] arm64: dts: salvator-common: Enable HS400 of SDHI2

To assist testing and review this patch and the above mentioned
dependencies, which are necessary and sufficient to enable HS400 on H3 /
Salvator-X, M3-W 1.0 / Salvator-X and H3 ES2.0 Salvator-XS are available
at:

https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git topic/hs400-v4

Changes since v3:
* As a follow-up to discussion with Ulf and Wolfram I have proposed
  two new HS400 tuning host operations. These are provided, and explained,
  in "mmc: core: more fine-grained hooks for HS400 tuning".

  The following driver patches have been updated to use these new operations.

  And "mmc: tmio: add eMMC HS400 mode support" proposes a minor cleanup
  to make it a little cleaner to add the proposed new host operations to
  the MMC core.

Changes since v2:
* Consolidate disable_scc and reset_hs400_mode into reset_hs400_tuning
  callback
* Reuse renesas_sdhi_reset_hs400_mode() in renesas_sdhi_hw_reset()
* Factor out renesas_sdhi_reset_scc()
