spi/spi-fsl-spi: reference correct pdata in fsl_spi_cs_control

2012-05-30T23:44:00Z

commit 067aa4815a9bc12a569d8a06afef50ba5773afbf upstream. Commit 178db7d3, "spi: Fix device unregistration when unregistering the bus master", changed spi device initialization of dev.parent pointer to be the master's device pointer instead of his parent. This introduced a bug in spi-fsl-spi, since its usage of spi device pointer was not updated accordingly. This was later fixed by commit 5039a86, "spi/mpc83xx: fix NULL pdata dereference bug", but it missed another spot on fsl_spi_cs_control function where we also need to update usage of spi device pointer. This change address that. Signed-off-by: Herton Ronaldo Krzesinski Acked-by: Joakim Tjernlund Signed-off-by: Grant Likely Signed-off-by: Ben Hutchings

spi-topcliff-pch: supports a spi mode setup and bit order setup by IO control

2012-05-20T21:56:44Z

commit f258b44e22e07f5e98ac2260c70acff5784791b6 upstream. This patch supports a spi mode setup and bit order setup by IO control. spi mode: mode 0 to mode 3 bit order: LSB first, MSB first Signed-off-by: Tomoya MORINAGA Signed-off-by: Grant Likely Signed-off-by: Ben Hutchings

spi-topcliff-pch: Fix issue for transmitting over 4KByte

2012-05-20T21:56:44Z

commit 7d05b3e868ee0f9231baf40cb77be3df5dd1f18c upstream. Currently, when spi-topcliff-pch receives transmit request over 4KByte, this driver can't process correctly. This driver needs to divide the data into 4Kbyte unit. This patch fixes the issue. Signed-off-by: Tomoya MORINAGA Signed-off-by: Grant Likely Signed-off-by: Ben Hutchings

spi/mpc83xx: fix NULL pdata dereference bug

2012-05-11T12:14:10Z

commit 5039a86973cd35bdb2f64d28ee12f13fe2bb5a4c upstream. Commit 178db7d3, "spi: Fix device unregistration when unregistering the bus master", changed device initialization to be children of the bus master, not children of the bus masters parent device. The pdata pointer used in fsl_spi_chipselect must updated to reflect the changed initialization.

spi: Fix device unregistration when unregistering the bus master

2012-05-11T12:14:09Z

commit 178db7d30f94707efca1a189753c105ef69942ed upstream. Device are added as children of the bus master's parent device, but spi_unregister_master() looks for devices to unregister in the bus master's children. This results in the child devices not being unregistered. Fix this by registering devices as direct children of the bus master.
