2010-08-04omap mailbox: Set a device in logical mbox instance for traceabilityHiroshi DOYU
With this patch, you'll get the following sysfs directories. This structure implies that a single platform device, "omap2-mailbox" holds multiple logical mbox instances. This could be the base to add sysfs files for each logical mboxes. Then userland application can access a mbox through sysfs entries if necessary(ex: setting kfifo size dynamically) ~# tree -d -L 2 /sys/devices/platform/omap2-mailbox/ /sys/devices/platform/omap2-mailbox/ |-- driver -> ../../../bus/platform/drivers/omap2-mailbox |-- mbox | |-- dsp <- they are each instances of logical mailbox. | |-- ducati | |-- iva2 | |-- mbox01 | |-- mbox02 | |-- mbox03 | |-- ..... | `-- tesla |-- power `-- subsystem -> ../../../bus/platform This was wrongly dropped by: commit c7c158e57bce6220644f2bcd65d82e1468aa40ec Signed-off-by: Hiroshi DOYU <Hiroshi.DOYU@nokia.com>
2010-08-04omap: mailbox: convert block api to kfifoOhad Ben-Cohen
The underlying buffering implementation of mailbox is converted from block API to kfifo due to the simplicity and speed of kfifo. The default size of the kfifo buffer is set to 256 bytes. This value is configurable at compile time (via CONFIG_OMAP_MBOX_KFIFO_SIZE), and can be changed at runtime (via the mbox_kfifo_size module parameter).

2010-08-04Mailbox: new mutext lock for h/w mailbox configurationHiroshi DOYU

2010-08-04omap: 3630: disable TLL SAR on 3630 ES1Anand Gadiyar
USBTLL Save-and-Restore is broken in 3630 ES1.0. Having it enabled could result in incorrect register restores as the OMAP exits off-mode. This could potentially result in unexpected wakeup events. (Refer 3630 errata ID i579) This is fixed in ES1.1. So disable it for ES1.0s.

Add revision detection for ES1.1 and ES1.2. Set default revision as ES1.2. Add CHIP_GE_OMAP3630ES1_1 to detect revisions 1.1 and later. This is needed for at least one feature that is broken in 3630ES1.0 but exists on older (3430 ES3.1) and newer revisions. Additionally, update some of the CHIP_GE_* macros to use other macros for ease of maintenance.

The only difference between them is the physical address of the uart4 port, which is only present in 36xx chips.

2010-08-04omap: Fix DEBUG_LL uart to access phys addr when MMU isn't enableJason Wang
Now we use a memory address to store the debug port info, So we need to read/write this address when we choose DEBUG_LL. When MMU isn't enable(I.E. the begining part of init stage of the linux kernel boot), we need to access physical address instead of virtual address, otherwise the kernel will crash.

2010-08-02omap: mux: fix multipath gpio handlingGrazvydas Ignotas
OMAP3530 CBB package can have GPIO126 muxed on 2 pins: mmc1_dat4 and cam_strobe. This causes a problem with current multipath GPIO mux handling, which muxes both pins as GPIO126 and makes the GPIO unusable. Fix this by not muxing any pins if multipath GPIO is detected and just print a warning instead. It's up to board files to set correct mux using omap_mux_init_signal and pin name.
