amba pl011: workaround for uart registers lockup

2011-06-16T19:01:57Z

This workaround aims to break the deadlock situation which raises during continuous transfer of data for long duration over uart with hardware flow control. It is observed that CTS interrupt cannot be cleared in uart interrupt register (ICR). Hence further transfer over uart gets blocked. It is seen that during such deadlock condition ICR don't get cleared even on multiple write. This leads pass_counter to decrease and finally reach zero. This can be taken as trigger point to run this UART_BT_WA. Workaround backups the register configuration, does soft reset of UART using BIT-0 of PRCC_K_SOFTRST_SET/CLEAR registers and restores the registers. This patch also provides support for uart init and exit function calls if present. Signed-off-by: Shreshtha Kumar Sahu Signed-off-by: Linus Walleij Signed-off-by: Greg Kroah-Hartman

ARM: 6758/1: amba: support pm ops

2011-02-23T16:26:46Z

Support pm_ops in the AMBA bus, required to allow drivers to use runtime pm. The implementation of AMBA bus pm ops is based on the platform bus implementation. Acked-by: Rafael J. Wysocki Acked-by: Linus Walleij Signed-off-by: Rabin Vincent Signed-off-by: Russell King

ARM: amba: make amba_driver id_table const

2011-02-23T16:24:22Z

Now that the bus level code deals with a const id table, we can also make the ID table in the amba_driver structure also const. Signed-off-by: Russell King

ARM: amba: make probe() functions take const id tables

2011-02-23T16:24:14Z

Make Primecell driver probe functions take a const pointer to their ID tables. Drivers should never modify their ID tables in their probe handler. Signed-off-by: Russell King

ARM: 6662/1: amba: make amba_bustype non-static

2011-02-23T16:24:08Z

Export amba_bustype struct so it can be used for things like registering bus notifiers. Signed-off-by: Rob Herring Signed-off-by: Russell King

ARM: clcd: add method for describing display capabilities

2011-02-19T11:09:05Z

The ARM CLCD PL110 controller in TFT mode provides two output formats based on whether the controller is in 24bpp mode or not - either 5551 or 888. PL111 augments this with a 444 and 565 modes. Some implementations provide an external MUX on the PL110 output to reassign the bits to achieve 565 mode. Provide a system of capability flags to allow the CLCD driver to work out what is supported by each panel and board, and therefore which display formats are permitted.

ARM: clcd: use amba_part() to determine if we have a PL110 primecell

2011-02-19T11:08:59Z

Instead of matching the entire peripheral ID, match against just the part number using the amba_xxx() macros. Acked-by: Catalin Marinas Signed-off-by: Russell King
