Subject: [PATCH v10 0/9] Turris Omnia MCU driver
Date: Fri, 10 May 2024 12:18:10 +0200 [thread overview]
Message-ID: <20240510101819.13551-1-kabel@kernel.org> (raw)
Hello Andy, Hans, Ilpo, Arnd, Gregory, and others,
this is v10 of the series adding Turris Omnia MCU driver.
This series still depends on the immutable branch between LEDs and
locking, introducing devm_mutex_init(), see the PR
https://lore.kernel.org/linux-leds/20240412084616.GR2399047@google.com/

Changes since v9:
- in functions where mcu->client is referred to multiple times added
a helper variable client = mcu->client, suggested by Andy
- changed instances of
if (!err)
do_something;
return err;
patterns to the more traditional pattern
if (err)
return err;
do_something;
return 0;
as suggested by Andy
- fixed some typos reported by Andy
- changed crc32_be(0xffffffff, ...) to crc32_be(~0, ...), as suggested
by Andy
- changed to use the DECI unit macro from units.h instead of hardcoded
10, as suggested by Andy
- changed -EINTR to -ERESTARTSYS in trng read and signature read
- changed the mutex lock in signature read to interruptible mutex lock,
as pointed out by Andy
