i2c: pnx: move header into the driver

2018-05-17T14:27:59Z

There are no platform_data users anymore. Move the structs into the driver. Signed-off-by: Wolfram Sang Acked-by: Vladimir Zapolskiy

i2c: pnx: Use devm_*() functions

2014-01-16T10:15:50Z

Use devm_*() functions to make cleanup paths simpler, and remove redundant return value check of platform_get_resource() because the value is checked by devm_ioremap_resource(). Signed-off-by: Jingoo Han Signed-off-by: Wolfram Sang

i2c: pnx: Fix read transactions of >= 2 bytes

2012-09-12T15:52:44Z

On transactions with n>=2 bytes, the controller actually wrongly clocks in n+1 bytes. This is caused by the (wrong) assumption that RFE in the Status Register is 1 iff there is no byte already ordered (via a dummy TX byte). This lead to the implementation of synchronized byte ordering, e.g.: Dummy-TX - RX - Dummy-TX - RX - ... But since RFE actually stays high after some Dummy-TX, it rather looks like: Dummy-TX - Dummy-TX - RX - Dummy-TX - RX - (RX) The last RX byte is clocked in by the bus controller, but ignored by the kernel when filling the userspace buffer. This patch fixes the issue by asking for RX via Dummy-TX asynchronously. Introducing a separate counter for TX bytes. Signed-off-by: Roland Stigge Signed-off-by: Wolfram Sang

i2c: Add device tree support to i2c-pnx.c

2012-04-22T09:59:47Z

This patch adds device tree support to the pnx-i2c driver by using platform resources for memory region and irq and removing dependency on mach includes. The following platforms are affected: * PNX * LPC31xx (WIP) * LPC32xx The patch is based on a patch by Jon Smirl, working on lpc31xx integration Signed-off-by: Roland Stigge Signed-off-by: Wolfram Sang

i2c-pnx.c: Use resources in platforms

2012-04-22T09:59:47Z

As a precondition for device tree conversion, the platforms using i2c-pnx.c are converted to using mem and irq resources instead of platform data. Signed-off-by: Roland Stigge Reviewed-by: Arnd Bergmann Signed-off-by: Wolfram Sang
