-+MIME-Version: 1.0
-+Content-Type: text/plain; charset=UTF-8
-+Content-Transfer-Encoding: 8bit
-+
-+Do not lock driver mutex in the global LED panel brightness sysfs
-+accessors brightness_show() and brightness_store().
-+
-+The mutex locking is unnecessary here. The I2C transfers are guarded by
-+I2C core locking mechanism, and the LED commands itself do not interfere
-+with other commands.

-+Subject: leds: turris-omnia: Do not use SMBUS calls
-+MIME-Version: 1.0
-+Content-Type: text/plain; charset=UTF-8
-+Content-Transfer-Encoding: 8bit
-+
-+The leds-turris-omnia driver uses three function for I2C access:
-+- i2c_smbus_write_byte_data() and i2c_smbus_read_byte_data(), which
-+  cause an emulated SMBUS transfer,
-+- i2c_master_send(), which causes an ordinary I2C transfer.
-+
-+The Turris Omnia MCU LED controller is not semantically SMBUS, it
-+operates as a simple I2C bus. It does not implement any of the SMBUS
-+specific features, like PEC, or procedure calls, or anything. Moreover
-+the I2C controller driver also does not implement SMBUS, and so the
-+emulated SMBUS procedure from drivers/i2c/i2c-core-smbus.c is used for
-+the SMBUS calls, which gives an unnecessary overhead.
-+
-+When I first wrote the driver, I was unaware of these facts, and I
-+simply used the first function that worked.
-+
-+Drop the I2C SMBUS calls and instead use simple I2C transfers.
