Subject: [PATCH 0/4] mmc: add pwrseq-based hw_reset
Date: Wed, 8 Feb 2017 22:45:52 +0100 [thread overview]
Message-ID: <db739bb8-2ad1-75bb-0b65-8246f84da7e8@gmail.com> (raw)
For implementing ops hw_reset in struct meson_host_ops often we can
use what is available in pwrseq already, just with a small extension.
For example all existing pwrseq drivers parse DT for a reset GPIO.
Meson GX is the first user of this extension.

mmc: pwrseq: add op reset to struct mmc_pwrseq_ops
mmc: pwrseq: implement reset operation in pwrseq_emmc
mmc: meson-gx: add pwrseq-based hw_reset
ARM64: dts: meson-gxbb-odroidc2: add hw-reset capability flag for emmc port
