* net: asix: Fix AX88772B when used with DriverModelJoshua Scott2016-09-09-0/+5
| | | | | | | | | | | | | | | | | | | A previous patch (net: asix: fix operation without eeprom) added a two-byte shift to the packet buffer when receiving a packet on the AX88772B. This shift was not included when the driver was updated to work with DriverModel. Testing on a Marvell DB-88F6820-ACM showed that the adapter was not functioning correctly (EHCI timeouts). This patch brings the two-byte shift to the DriverModel implementation of ops->recv (asix_eth_recv). Testing on the same board, we were able to TFTP a file over and confirm that the crc32 was correct.

* | serial: bcm283x_mu: Detect disabled serial deviceAlexander Graf2016-09-06-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the raspberry pi, you can disable the serial port to gain dynamic frequency scaling which can get handy at times. However, in such a configuration the serial controller gets its rx queue filled up with zero bytes which then happily get transmitted on to whoever calls getc() today. This patch adds detection logic for that case by checking whether the RX pin is mapped to GPIO15 and disables the mini uart if it is not mapped properly. That way we can leave the driver enabled in the tree and can determine during runtime whether serial is usable or not, having a single binary that allows for uart and non-uart operation.

* | sunxi: display: Use PWM to drive backlight where applicableHans de Goede2016-08-26-0/+11
|/ | | | | | | | | | | | | | | | | | | | | 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.

* | spi: tegra: fix hang in set_mode()Stephen Warren2016-08-25-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | 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.
