Subject: [PATCH V3 0/3] mmc: mmci: add busy detect for stm32 sdmmc variant
Date: Mon, 3 Jun 2019 17:55:22 +0200 [thread overview]
Message-ID: <1559577325-19266-1-git-send-email-ludovic.Barre@st.com> (raw)
From: Ludovic Barre <ludovic.barre@st.com>
This patch series adds busy detect for stm32 sdmmc variant.
Some adaptations are required:
-Clear busy status bit if busy_detect_flag and busy_detect_mask are
different.
-Add hardware busy timeout with MMCIDATATIMER register.
V3:
-rebase on latest mmc next
-replace re-read by status parameter.
V2:
-mmci_cmd_irq cleanup in separate patch.
-simplify the busy_detect_flag exclude
-replace sdmmc specific comment in
"mmc: mmci: avoid fake busy polling in mmci_irq"
to focus on common behavior
