| * spi: fsl_qspi: Fix qspi_op_rdsr memcpy issueGong Qianyu2016-01-27-3/+3
| | | | | | | | | | | | | | | | | | | | In current driver, we always copy 4 bytes to the dest memory. Actually the dest memory may be shorter than 4 bytes. Add an argument to indicate the dest memory length. Avoid writing memory outside of the bounds. Signed-off-by: Gong Qianyu <Qianyu.Gong@freescale.com> Reviewed-by: York Sun <york.sun@nxp.com>

| | | | | | | | | | | | | | | | | | | | | | In current driver everytime we memcpy 4 bytes to the dest memory regardless of the remaining length. This patch adds checking the remaining length before memcpy. If the length is shorter than 4 bytes, memcpy the actual length of data to the dest memory.

* | dm: x86: spi: Convert ICH SPI driver to driver model PCI APISimon Glass2016-01-24-116/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present this SPI driver works by searching the PCI buses for its peripheral. It also uses the legacy PCI API. In addition the driver has code to determine the type of Intel PCH that is used (version 7 or version 9). Now that we have proper PCH drivers we can use those to obtain the information we need. While the device tree has a node for the SPI peripheral it is not in the right place. It should be on the PCI bus as a sub-peripheral of the LPC device. Update the device tree files to show the SPI controller within the PCH, so that PCI access works as expected.
