Subject: [PATCH 0/3] mmc: sunxi: Changes in the host driver
Date: Thu, 21 Jul 2016 08:28:01 +0200 [thread overview]
Message-ID: <cover.1469082481.git.moinejf@free.fr> (raw)
While testing the eMMC access in a Banana Pi M3, I found and fixed
some problems:
- the driver was trying to set a strange rate when clk_round_rate()
was returning an error
- the 'new timing mode' could not work because a register was not set
- with a parent clock at 1.2GHz, the output and sample phases were
not correct for the A83T
Jean-Francois Moine (3):
mmc: sunxi: Check the value returned by clk_round_rate
mmc: sunxi: Set the 'New Timing' register for 8 bits DDR transfers
mmc: sunxi: Add support to the Allwinner A83T
