To describe the pixel format on the hardware bus between display interface and encoders, use media bus formats, which are more expressive.

| * | clk: socfpga: add divider registers to the main pll outputsEnrico Jorns2016-08-181-3/+22
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is based on kernel patch 0691bb1b5a1865b3bbc9b7ce6e26eff546abb1cf by Dinh Nguyen <dinguyen@altera.com>. The C0(mpu_clk), C1(main_clk), and C2(dbg_base_clk) outputs from the main PLL go through a pre-divider before coming into the system. These registers were hidden for the CycloneV platform, but are now used for the ArriaV platform. This patch updates the clock driver to read the div-reg property for the socfpga-periph-clk clocks. Note: The registers used for the div-reg property are not documented but set by the preloader.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the Linux kernel and the qemu code, the MMCIFIFOCNT contains the remaining number of words to read, excluding those that are already in the FIFO. So the current number of bytes in the FIFO is host_remain - (readl(base + MMCIFIFOCNT) << 2). Also writing to MMCIDATACTRL will reset the read counter. As a result, MCI_DATABLOCKEND is never set and read_bytes() waits forever. With this change, SD-Card support on qemu vexpress works correctly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'brightness-levels' in the device tree. In case of an empty 'brightness-levels' array in the device tree or a non empty one but containing only zeros the value of 'pwm_backlight->scale' would remain 0 possibly causing a division by zero in the function compute_duty_cycle(). To fix it we check the computed value in case we actually have a 'brightness-levels' array in the device tree otherwise we implicitly assume a simple array of the form { 0, 1, 2, ..., 100 } and set the scale to 100.

Regarding barebox, the differences boil down to the location and length of the CHIP SELECT and BIT COUNT/BURST LENGTH elements of CONREG. The spi_ver_0_4 variant is limited to single word bursts with a maximum of 32 bits_per_word. Add support for the i.MX31 SPI interface to the barebox spi_ver_0_7 implementation.
