spi: Add spi_write_then_read

2019-09-16T02:39:22Z

Add support for SPI synchronous write followed by read, this is common interface call from spi-nor to spi drivers. Reviewed-by: Simon Glass Signed-off-by: Jagan Teki Tested-by: Adam Ford #da850-evm

spi: Kconfig: Unmark DEPRECATED for MXS_SPI

2019-09-16T02:39:22Z

MXS_SPI driver now partially converted into driver-model, so unmark the DEPRECATED option for the same. Signed-off-by: Lukasz Majewski [jagan: update the commit message] Signed-off-by: Jagan Teki Reviewed-by: Jagan Teki

spi: soft_spi: Fix data abort if slave is not probed

2019-09-16T02:39:22Z

In case spi_get_bus_and_cs callback is used, spi bus is first probed then slave devices are probed. To avoid a data abort in soft_spi probe function, we need to check that (slave != NULL). If slave is NULL, cs_flags and clk_flags will be initialized with respectively GPIOD_ACTIVE_LOW and 0. Signed-off-by: Christophe Kerello Signed-off-by: Patrice Chotard Reviewed-by: Jagan Teki

spi: mvebu_a3700_spi: Fix clock prescale computation

2019-09-16T02:39:22Z

The prescaler value computation can yield wrong result if given 0x1f at the beginning: the value is computed to be 0x20, but the maximum value the register can hold 0x1f, so the actual stored value in this case is 0, which is obviously wrong. Set the upper bound of the value to 0x1f with the min macro. Signed-off-by: Marek Behún Reviewed-by: Stefan Roese Reviewed-by: Jagan Teki

x86: ich-spi: Convert driver to spi-mem ops

2019-08-09T14:24:02Z

With the introduction of the new spi-mem model operations changed slightly. The new spi-mem operations make things a bit easier to handle for ich-spi flash interface. This patch converts the ich-spi driver by using spi-mem operations.

spi: Drop obsolete mtk_qspi driver references

2019-07-25T13:22:20Z

Since u-boot has added the spi-mem framework and replaced the spi-nor framework, the mtk_qspi is no longer compatible with the new spi-nor driver. Remove this driver along with replacing config item with new mtk spi-nor driver.
