2008-07-20Subject: [PATCH 2/2] atmel_serial: Implement flush_buffer() hookHaavard Skinnemoen
Avoid dumping garbage to the serial port when the tty is flushed. This tends to happen when rebooting from a serial console. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com> Acked-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-07-20Subject: [PATCH 1/2] serial: Add flush_buffer() operation to uart_opsHaavard Skinnemoen
Serial drivers using DMA (like the atmel_serial driver) tend to get very confused when the xmit buffer is flushed and nobody told them. They also tend to spew a lot of garbage since the DMA engine keeps running after the buffer is flushed and possibly refilled with unrelated data. This patch adds a new flush_buffer operation to the uart_ops struct, along with a call to it from uart_flush_buffer() right after the xmit buffer has been cleared. The driver can implement this in order to syncronize its internal DMA state with the xmit buffer when the buffer is flushed.

2008-07-20mfd: let asic3 use mem resource instead of bus_shiftPhilipp Zabel
The bus_shift parameter in platform_data is not needed as we can tell the driver with the IOMEM_RESOURCE whether the ASIC is located on a 16bit or 32bit memory bus. The htc-egpio driver uses a more descriptive bus_width parameter, but for drivers where the register map size fixed, we don't even need this.

2008-07-20mfd: add ASIC3_CONFIG_GPIO templatesPhilipp Zabel
As ASIC3 GPIO alternate function configuration is expected to be similar for several devices, it is convenient to define descriptive macros. This patch is inspired by the PXA MFP configuration, the alternate functions were observed on hx4700 and blueangel.

2008-07-20r8169: avoid thrashing PCI conf space above RTL_GIGA_MAC_VER_06Marcus Sundberg
The magic write to register 0x82 will often cause PCI config space on my 8168 (PCI ID 10ec:8168, revision 2. mounted in an LG P300 laptop) to be filled with ones during driver load, and thus breaking NIC operation until reboot. If it does not happen on first driver load it can easily be reproduced by unloading and loading the driver a few times. The magic write was added long ago by this commit: Author: François Romieu <romieu@fr.zoreil.com> Date: Sat Jan 10 06:00:46 2004 -0500 [netdrvr r8169] Merge of changes done by Realtek to rtl8169_init_one(): - phy capability settings allows lower or equal capability as suggested in Realtek's changes; - I/O voodoo; - no need to s/mdio_write/RTL8169_WRITE_GMII_REG/; - s/rtl8169_hw_PHY_config/rtl8169_hw_phy_config/; - rtl8169_hw_phy_config(): ad-hoc struct "phy_magic" to limit duplication of code (yep, the u16 -> int conversions should work as expected); - variable renames and whitepace changes ignored. As the 8168 wasn't supported by that version this patch simply removes the bogus write from mac versions <= RTL_GIGA_MAC_VER_06. [The change above makes sense for the 8101/8102 too -- Ueimor] Signed-off-by: Marcus Sundberg <marcus@ingate.com> Signed-off-by: Francois Romieu <romieu@fr.zoreil.com>
2008-07-20r8169: multicast register updateFrancois Romieu
The layout of the 8101 series is identical to that of the 8168 one, thus allowing to pack everything not 8169 related above MAC_VER_06. New 810x and 8168 chipsets should automagically behave correctly. It matches code in Realtek's 1.008.00 8101 and 8.007.00 8168 drivers. Signed-off-by: Francois Romieu <romieu@fr.zoreil.com>
