The driver uses the as fast as it can approach
to drive the SCK signal. However this does not
work with certain low speed SPI chips (e.g. the
PCF2123 RTC chip).
The patch adds per-bit slowdowns in order to be
able to use the driver with such chips as well.

The 'ath79_spi_txrx_mode0' function does not
set the SCK signal to LOW at the end of a word
transfer. This causes communications errors with
certain devices (e.g. the PCF2123 RTC chip).
The patch ensures that the SCK signal will be LOW.

Use gpio_request_one() instead of multiple gpiolib calls.

This patch set contain various fixes for the spi-ath79 driver.
Gabor Juhos (6):
spi/ath79: add delay between SCK changes
spi/ath79: add missing HIGH-LOW SCK transition
spi/ath79: remove superfluous chip select code
spi/ath79: use gpio_request_one
spi/ath79: avoid multiple initialization
The spi_bitbang driver calls the chipselect function
of the driver from spi_bitbang_setup in order to
deselect the given SPI chip, so we don't have to
initialize the CS line here.

Mostly looks okay to me. A few comments below. Do you want this one
