reset: uniphier: fix compatible for SD reset node for LD11/LD20

2017-08-30T00:07:04+00:00

LD20 has SD ctrl instead of MIO ctrl.  LD11 has both of them.

reset: uniphier: refactor reset data and add NAND/eMMC reset lines

2017-08-20T14:06:20+00:00

  - Merge sys_reset data of LD4, Pro4, sLD8 and Pro5

  - Merge sys_reset data of LD11 and LD20

  - Use primitive UNIPHIER_RESETX() macro because bit assignments for
    system reset will be changed for every SoC in the future

  - Add NAND and eMMC resets

ARM: uniphier: remove sLD3 SoC support

2017-08-20T14:05:39+00:00

This SoC is too old.  It is difficult to maintain any longer.

reset: add reset_request()

2017-07-28T21:34:06+00:00

This is needed in error path to assert previously deasserted
reset by using a saved reset_ctl reference.

ARM: uniphier: fix various sparse warnings

2017-06-24T21:06:09+00:00

Fix warnings reported by sparse:
 - ... was not declared. Should it be static?"
 - cast to restricted __be32

While fixing those, the type conflict of cci500_init() was found.

reset: sti: add deassert counter in reset channel descriptor

2017-06-05T18:13:02+00:00

This deassert counter allow to manage "shared" reset lines
encountered in some specific case. On STiH410 SoC, DWC3,
EHCI and OHCI are all using a respective PHY, but all of
these PHYs shared a "global" reset.

Currently, during command "usb stop", all host controller are
stopped (XHCI, EHCI and OHCI). XHCI is first shutdowned, which
means that PHY global reset is asserted. Then EHCI is shutdowned,
but its PHY reset has already been asserted which make handshake()
call failed in ehci_shutdown().

This counter allows to really assert a reset lines only when the
"last" user is asserting it.

dm: Rename dev_addr..() functions

2017-06-01T13:03:01+00:00

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.
