Hi, This is the v2 of the RFC for UART4 addition for 3630 chips. Changes with respect to v1 [1]: - Added AUTOIDLE handling. - Added respective entries to prcm_setup_regs. Indirect dependencies: - Tested with Thomas Weber's patch [2]. Known issues: - After enabling earlyprintk in 3630sdp, this is shown in the logs during bootup: --- LOG START --- Unhandled fault: imprecise external abort (0x1c06) at 0xc000e71c Internal error: : 1c06 [#1] last sysfs file: Modules linked in: CPU: 0 Not tainted (2.6.33-rc8-07945-gac969e9 #13) PC is at init_timer_key+0x0/0x1c LR is at omap_serial_init_port+0xdc/0x2d4 pc : [<c005cee0>] lr : [<c000e54c>] psr: 60000013 sp : cf823f70 ip : d0800000 fp : c0381b68 r10: c0381ed0 r9 : 00000360 r8 : c0381ec8 r7 : 00000015 r6 : 00000000 r5 : 00000020 r4 : c0381b08 r3 : c0035db8 r2 : 00000000 r1 : 00000000 r0 : c0381ed0 Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment kernel Control: 10c5387f Table: 80004019 DAC: 00000017 Process swapper (pid: 1, stack limit = 0xcf8222e8) Stack: (0xcf823f70 to 0xcf824000) 3f60: 00000003 fb020000 c0381aa8 00000004 3f80: 00000004 c000b380 00000000 00000000 00000000 00000000 00000000 c000e76c 3fa0: c00232e4 00000000 c000b380 c000fd78 c00232e4 c000fca4 c00232e4 c000b398 3fc0: c00232e4 c002b33c 00000031 00000000 00000000 00000192 00000000 c00232e4 3fe0: 00000000 00000000 00000000 c0008578 00000000 c002cdbc 00000000 00000000 [<c005cee0>] (init_timer_key+0x0/0x1c) from [<c000e54c>] (omap_serial_init_port+0xdc/0x2d4) [<c000e54c>] (omap_serial_init_port+0xdc/0x2d4) from [<c000e76c>] (omap_serial_init+0x28/0x34) [<c000e76c>] (omap_serial_init+0x28/0x34) from [<c000fd78>] (zoom_peripherals_init+0x44/0x68) [<c000fd78>] (zoom_peripherals_init+0x44/0x68) from [<c000fca4>] (omap_sdp_init+0x14/0x50) [<c000fca4>] (omap_sdp_init+0x14/0x50) from [<c000b398>] (customize_machine+0x18/0x24) [<c000b398>] (customize_machine+0x18/0x24) from [<c002b33c>] (do_one_initcall+0x5c/0x1b4) [<c002b33c>] (do_one_initcall+0x5c/0x1b4) from [<c0008578>] (kernel_init+0x90/0x10c) [<c0008578>] (kernel_init+0x90/0x10c) from [<c002cdbc>] (kernel_thread_exit+0x0/0x8) Code: e5801004 e5831000 e5813004 e12fff1e (e3a03000) ---[ end trace 1b75b31a2719ed1c ]--- Kernel panic - not syncing: Attempted to kill init! --- LOG END --- Detailed patchlist summary: Sergio Aguirre (5): ARM: OMAP3630: PRCM: Add UART4 control bits OMAP clock: Add UART4 autoidle bit for 3630 OMAP clock: Add uart4_ick/fck definitions for 3630 OMAP3: PRCM: Consider UART4 for 3630 chip in prcm_setup_regs omap3: serial: Add uart4 wakeup handling arch/arm/mach-omap2/clock3xxx_data.c | 22 ++++++++++++++++++++++ arch/arm/mach-omap2/cm-regbits-34xx.h | 2 ++ arch/arm/mach-omap2/pm34xx.c | 8 ++++++-- arch/arm/mach-omap2/prcm-common.h | 4 ++++ arch/arm/mach-omap2/serial.c | 4 ++++ 5 files changed, 38 insertions(+), 2 deletions(-) Regards, Sergio [1] http://marc.info/?l=linux-omap&m=126710887505294&w=2 [2] http://marc.info/?l=linux-kernel&m=126709078514087&w=2 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
