Subject: [PATCH 0/2] sd: sdhci: Implement basic vendor specific register support
Date: Tue, 2 Jun 2020 22:24:02 -0700 [thread overview]
Message-ID: <20200603052404.30788-1-linux@roeck-us.net> (raw)
The Linux kernel's IMX code now uses vendor specific commands.
This results in endless warnings when booting the Linux kernel.
sdhci-esdhc-imx 2194000.usdhc: esdhc_wait_for_card_clock_gate_off:
card clock still not gate off in 100us!.
Implement support for the vendor specific command implemented in IMX
SDHCI hardware to be able to avoid this warning.
Patch 1/2 implements vendor specific command support in the SDHCI core
code. At this time, only IMX vendor command support is implemented,
but the implementation is written with expandability in mind.
Patch 2/2 enables IMX SDHCI vendor extensions for all affected emulations.
