Subject: [PATCH 00/11] Initital support for new power/perf features for SD cards
Date: Tue, 4 May 2021 18:12:11 +0200 [thread overview]
Message-ID: <20210504161222.101536-1-ulf.hansson@linaro.org> (raw)
In the SD spec v4.x the SD function extension registers were introduced,
together with a new set of commands (CMD48/49 and CMD58/59) to read and write
to them.
Moreover, in v4.x a new standard function for power management features were
added, while in v6.x a new standard function for performance enhancements
features were added.
This series implement the basics to add support for these new features (and
includes some additional preparations in patch 1->7), by adding support for
reading and parsing these new SD registers. In the final patch we add support
for the SD poweroff notification feature, which also add a function to write to
these registers.
Note that, there are no HW updates need for the host to support reading/parsing
of the these new SD registers. This has been tested with a 64GB Sandisk Extreme
PRO UHS-I A2 card.
Tests and reviews are of course greatly appreciated!
Kind regards
Ulf Hansson
