2016-08-26sunxi: display: Use PWM to drive backlight where applicableHans de Goede
When the backlight's pwm input is connected to a pwm output of the SoC, actually use pwm to drive the backlight. The mean reason for doing this is to fix the backlight turning off for aprox. 1 second while the kernel is booting. This is caused by the kernel actually using pwm to drive the backlight, so that it can dim the backlight. First the pwm driver loads and switches the pinmux for the pin driving the backlight's pwm input to the pwm controller. Then about 1s later the actual backlight driver loads and tells the pwm driver to actually update the pwm settings, which have a power-on-reset value of "off". An additional advantage is that this allows us to initatiate the backlight at 80%, which is the kernel default, avoiding a brightness change while the kernel loads.

2016-08-25spi: tegra: fix hang in set_mode()Stephen Warren
In tegra20_slink.c, the set_mode() function may be executed before the SPI bus is claimed the first time, and hence the clocks to the SPI controller may not be running. If so, any register read/write at this time will hang the CPU. Fix this by ensuring the clock is running as soon as the driver is probed. This is observed on the Tegra30 Beaver board. Apply the same clock initialization fix to all other Tegra SPI drivers so that if set_mode() is ever implemented there, the same bug will not appear. Note that tegra114_spi.c already operates in this fashion. The clock manipulation code is copied from claim_bus() to probe() rather than moved. This ensures that any calls to set_speed() take effect; the clock can't be set once during probe and left unchanged.

2016-08-22net: davinci_emac: Restore the internal MDIO accessors return valueskarl beldan
The spatch series converting legacy drivers from miiphy_register to mdio_register changed the return convention of the davinci_emac internal MDIO accessors, making the internal code relying on it misbehaving: no mdiodev get registered and U-Boot crashes when using net cmds in the context of the old legacy net API. ATM davinci_emac_initialize and cpu_eth_init don't return a proper value in that case but fixing them would not avoid the crash. This change is just a follow-up to the spatch pass, the MDIO accessors of the mdiodev introduced by the spatch pass retain their proper values.

Commit 302c5db ("dm: tpm: Add Driver Model support for tpm_atmel_twi driver") converted the Atmel TWI TPM driver itself to driver model, but kept the legacy-style i2c_write/i2c_read calls. Commit 3e7d940 ("dm: tpm: Every TPM drivers should depends on DM_TPM") then made DM_I2C a dependency of the driver, effectively forcing users to turn on CONFIG_DM_I2C_COMPAT to get it to work. This patch adds the necessary dm_i2c_write/dm_i2c_read calls to make the driver compatible with DM, but also keeps the legacy calls in ifdefs, so that the driver is now compatible with both DM and non-DM setups.
