Hi everyone,
This is the second version of the clockdomain patches. It:
. adds the IVA1 clockdomain in the DSP powerdomain, for OMAP2420 only
. replaces omap_type_t typedef with struct omap_chip_id
. removes all EXPORT_SYMBOLs - these can be added back in if clockdomain
code needs to be used from loadable PM modules - the expectation is that
it will only be used from PM code
. creates _clkdm_lookup() to avoid potential race in clkdm_register()
. fixes several clockdomain platform flag bugs
. gets rid of tabs in comments
. is refreshed against current git head (e015fc7)
This version is tested against 3430SDP ES2.1, and compile-tested with
N800 and 2430SDP configs. Size, diffstat have been updated below.
Thanks to Tony & Jouni for review and comments. More comments welcome,
- Paul
-------------------------
Hello,
this patch series adds a hardware control interface for OMAP2/3
clockdomains. Also added is clockdomain usecounting of underlying
clocks, so hardware-supervised and software-supervised clockdomain
transitions can occur correctly. The interface is fully documented in
the code.
24xx clocks are not yet linked with clockdomains. This will be done in
a later patchset.
This series must be applied after the powerdomain series, posted earlier.
Clockdomain code tested on 3430SDP ES2.1; also boot-tested on N800.
Many people at Nokia and TI provided commentary and review during the
development of the clockdomain patches. Particular help came from (in
alphabetical order): Karthik Dasu, Tony Lindgren, Rajendra Nayak,
Sakari Poussa, Igor Stoppa, and Richard Woodruff. Jouni Högander
merits special mention; he took the original code and made it do what
it was supposed to do on the hardware, testing and fixing many bugs.
