Subject: [PATCH v5 00/12] mmc: Add support to Marvell Xenon SD Host Controller
Hello,
This the fifth version of the series adding support for the SDHCI
Xenon controller. It can be currently found on the Armada 37xx and the
Armada 7K/8K but will be also used in more Marvell SoC (and not only
the mvebu ones actually).
v4->v5:
- Remove the patch to export sdhci_execute_tuning(). It is already
exported in v4.10.
- Introduce a patch adding a missing clock for the sdhci controller
present on the CP master for A7K/A8K. There is no build dependency
but obviously this patch is need to use the sdhci controller present
on the CP part.
- Adjust Xenon return setup, to avoid being overwritten by
sdhci_add_host().
- Change Xenon register definition prefix to "XENON_".
- Fix typos in Xenon driver and dt-binding docs.
- Change compatible string "marvell,armada-7000-sdhci" to
"marvell,armada-8k-sdhci". Actually the Armada 7K SoCs are a subset
of the Armada 8K SoCs. Moreover, the use of the '000' is not
consistent with all the other compatible string already used for the
Armada 7K/8K family.
- Added the Tested-by from Russell King on an Armada 8K based board.
v3 -> v4:
For this version a few change have been done:
- fixes 2 bug reported by kbuild-bot
- remove extra of_node_put()
- convert 0 in false for function returning boolean
- add a device tree node for the sdhci controller present on the CP
master for A7K/A8K. It also led to rename the sdhci0 node on AP to
ap_sdhci0 to make a distinction with the one present on CP master.
v2 -> v3
I think that now most (if not all) the remarks had been taking into
account since the second version. According to Ziji Hu, here are the
following changes:
" Changes in V3:
Adjust and improve Xenon DT bindings. Move some caps setting from driver into
DT. Use mmc-card sub-node to represent eMMC type.
Remove PHY Sampling Fixed Delay Line scan in lower speed mode.
Improve Xenon probe and ->init_card() functions.
Export sdhci_enable_sdio_irq() and implement own SDIO IRQ control.
Split PHY patch into two smaller patches.
Temporarily remove AXI clock before its implementation is improved."
Besides this changes I also
- Removed the sdhci-xenon-phy.h and moved its content in the
shc-xenon-phy.c file.
- Fixed the tuning-count usage
- Managed the error case for clk_prepare_enable
For the record the change from v1 was:
" Changes in V2:
rebase on v4.9-rc2.
Re-write Xenon bindings. Ajust Xenon DT property naming.
Add a new DT property to indicate eMMC card type, instead of using
variable card_candidate.
Clear quirks SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12 in Xenon platform data
Add support to HS400 retuning."
Thanks,
Gregory
