+Subject: [PATCH 02/35] MIPS: ath79: separate common PCI code
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The 'pcibios_map_irq' and 'pcibios_plat_dev_init'
+are common functions and only instance one of them
+can be present in a single kernel.
+
+Currently these functions can be built only if the
+CONFIG_SOC_AR724X option is selected. However the
+ath79 platform contain support for the AR71XX SoCs,.
+The AR71XX SoCs have a differnet PCI controller,
+and those will require a different code.
+
+Move the common PCI code into a separeate file in
+order to be able to use that with other SoCs as
+well.

+The current code unconditionally registers the AR724X

+
+Add a common function for PCI controller registration,
+and only register the AR724X PCI controller if the kernel
+is running on an AR724X SoC.

+Subject: [PATCH 10/35] MIPS: ath79: fix broken ar724x_pci_{read,write} functions
+
+The current ar724x_pci_{read,write} functions are
+broken. Due to that, pci_read_config_byte returns
+with bogus values, and pci_write_config_{byte,word}
+unconditionally clears the accessed PCI configuration
+registers instead of changing the value of them.
+
+The patch fixes the broken functions, thus the PCI
+configuration space can be accessed correctly.

+Subject: [PATCH 11/35] MIPS: ath79: add a workaround for a PCI controller bug in AR7240 SoCs
+
+The PCI controller of the AR724X SoCs has a hardware
+bag. If the BAR0 register of the PCI device is set to
+the proper base address, the memory address space of
+the device is not accessible.
+
+When the device driver tries to access the memory
+address space of the PCI device, it leads to data
+bus error, similiar to this:
+

+
+This can be avoided by calling the 'ar724x_pci_add_data'
+function from the board specific setup code. However it
+makes no sense to use that function for every board,
+especially when the board does not needs to set the
+platform_data field of any PCI device.
+
+The patch allows the board setup code to specify a board
+specific function if that is required.
+
+Signed-off-by: Gabor Juhos <juhosg@openwrt.org>
+
+v2: - no changes
+
+The pci_irq_map function can throw another NULL pointer
+dereference, that will be fixed in a subsequent patch.

+Subject: [PATCH 17/35] MIPS: ath79: allow to use SoC specific PCI IRQ maps
+
+The PCI controllers in the AR71XX and in the
+AR724X SoCs are different, and both of them
+uses different IRQ wiring.
+
+The patch modifies the 'pcibios_map_irq' function
+in order to allow to use different IRQ maps for
+the different SoCs. The patch also adds a function,
+which lets the board setup code to override the
+default IRQ map.

+Subject: [PATCH 26/35] MIPS: ath79: rework IP2/IP3 interrupt handling
+
+The current implementation assumes that flushing the
+DDR writeback buffer is required for IP2/IP3 interrupts,
+however this is not true for all SoCs.
+
+Use SoC specific IP2/IP3 handlers instead of flushing
+the buffers in the dispatcher code.

+Subject: [PATCH 32/35] MIPS: ath79: add PCI_AR724X Kconfig symbol
+
+The AR724X specific PCI code can be used for the
+AR934X SoCs, however it can be selected only if
+SOC_AR724X is set.
+
+Introduce a new Kconfig symbol in order to be able
+to use the code for AR934X as well.

+Subject: [PATCH 1/7] spi/ath79: add delay between SCK changes
+
+The driver uses the "as fast as it can" approach
+to drive the SCK signal. However this does not
+work with certain low speed SPI chips (e.g. the
+PCF2123 RTC chip). Add per-bit slowdowns in order
+to be able to use the driver with such chips as
+well.

+
+The spi_bitbang driver calls the chipselect function
+of the driver from spi_bitbang_setup in order to
+deselect the given SPI chip, so we don't have to
