*	mailbox: constify mbox_chan_ops structures	Bhumika Goyal	2017-03-28	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Check for mbox_chan_ops structures that are only stored in the ops field of a mbox_controller structure. This field is of type const struct mbox_chan_ops *, so mbox_chan_ops structures having this property can be declared as const. Done using Coccinelle: @r1 disable optional_qualifier @ identifier i; position p; @@ struct mbox_chan_ops i@p = {...}; @ok1@ identifier r1.i; struct hi6220_mbox mbox; struct slimpro_mbox ctx; position p; @@ ( mbox.controller.ops=&i@p \| ctx.mb_ctrl.ops=&i@p ) @bad@ position p!={r1.p,ok1.p}; identifier r1.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r1.i; @@ +const struct mbox_chan_ops i; File size details: text data bss dec hex filename 2310 248 0 2558 9fe drivers/mailbox/hi6220-mailbox.o 2366 192 0 2558 9fe drivers/mailbox/hi6220-mailbox.o 1500 248 0 1748 6d4 mailbox/mailbox-xgene-slimpro.o 1556 192 0 1748 6d4 mailbox/mailbox-xgene-slimpro.o Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
*	mailbox: Hi6220: add mailbox driver	Leo Yan	2016-03-04	1	-0/+395
	Add driver for Hi6220 mailbox, the mailbox communicates with MCU; for sending data, it can support two methods for low level implementation: one is to use interrupt as acknowledge, another is automatic mode which without any acknowledge. These two methods have been supported in the driver. For receiving data, it will depend on the interrupt to notify the channel has incoming message. Now mailbox driver is used to send message to MCU to control dynamic voltage and frequency scaling for CPU, GPU and DDR.
