* serial: convert early_uart to earlycon for 8250Yinghai Lu2007-07-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Beacuse SERIAL_PORT_DFNS is removed from include/asm-i386/serial.h and include/asm-x86_64/serial.h. the serial8250_ports need to be probed late in serial initializing stage. the console_init=>serial8250_console_init=> register_console=>serial8250_console_setup will return -ENDEV, and console ttyS0 can not be enabled at that time. need to wait till uart_add_one_port in drivers/serial/serial_core.c to call register_console to get console ttyS0. that is too late. Make early_uart to use early_param, so uart console can be used earlier. Make it to be bootconsole with CON_BOOT flag, so can use console handover feature. and it will switch to corresponding normal serial console automatically. new command line will be: console=uart8250,io,0x3f8,9600n8 console=uart8250,mmio,0xff5e0000,115200n8 or earlycon=uart8250,io,0x3f8,9600n8 earlycon=uart8250,mmio,0xff5e0000,115200n8 it will print in very early stage: Early serial console at I/O port 0x3f8 (options '9600n8') console [uart0] enabled later for console it will print: console handover: boot [uart0] -> real [ttyS0] Signed-off-by: <yinghai.lu@sun.com> Cc: Andi Kleen <ak@suse.de> Cc: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: Russell King <rmk@arm.linux.org.uk> Cc: Gerd Hoffmann <kraxel@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | On some motherboards ACPI C3 is available, but it isn't causing frequency transition on VIA Nehemiah. Longhaul wasn't working at all earlier, but due to scaling_cur_speed returning true CPU frequency now, it looks like CPU is getting stuck at highest frequency since 2.6.21. I didn't find a reason.

This patch moves the specific code to pxa25x.c and pxa27x.c and makes dma.c more generic. 1. add pxa_init_dma() for dma initialization, the number of channels are passed in by the argument 2. add a "prio" field to the "struct pxa_dma_channel" for the channel priority, and is initialized in pxa_init_dma() 3. use a general priority comparison with the channels "prio" field so to remove the processor specific pxa_for_each_dma_prio macro, this is not lightning fast as the original one, but it is acceptable as it happens when requesting dma, which is usually not so performance critical Signed-off-by: eric miao <eric.miao@marvell.com> Acked-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Another point is that GPIO85- GPIO95 bits within GEDR2 will also be masked out on PXA25x Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

PXA_IRQ_SKIP is defined to be 7 on PXA25x so that the first IRQ starts from zero. This makes IRQ numbering inconsistent between PXA25x and PXA27x. Remove this macro so that the same IRQ_XXXXX definition has the same value on both PXA25x and PXA27x. 2. make IRQ_SSP3..IRQ_PWRI2C valid only if PXA27x is defined, this avoids unintentional use of these macros on PXA25x Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
