* ARM i.MX6Q: fix network configuration for Protonic PRTI6G boardOleksij Rempel2020-12-071-0/+18
| | | | | | | | | By default the iMX6UL is configured to output clock on the ENET1_TX_CLK pin. Since on the Protonic PRTI6G board the PHY is actual refclock provider, we should change the clock source to the external clock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend our syscon API with a device_node_to_regmap function that has the same semantics as upstream: __________________________________________________________________________ | Linux commit 39233b7c611248c0d05209b4854bc63e26485655 | CommitDate: Thu Aug 8 15:30:07 2019 -0700 | | mfd/syscon: Add device_node_to_regmap() | | device_node_to_regmap() is exactly like syscon_node_to_regmap(), but it | does not check that the node is compatible with "syscon", and won't | attach the first clock it finds to the regmap. | | The rationale behind this, is that one device node with a standard | compatible string "foo,bar" can be covered by multiple drivers sharing a | regmap, or by a single driver doing all the job without a regmap, but | these are implementation details which shouldn't reflect on the | devicetree. | | Signed-off-by: Paul Cercueil <paul@crapouillou.net> | Acked-by: Arnd Bergmann <arnd@arndb.de> | Signed-off-by: Paul Burton <paul.burton@mips.com> |__________________________________________________________________________ Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* syscon: Do not return NULL when driver is not selectedAndrey Smirnov2016-05-181-2/+2
| | | | | | | | | | | Both syscon_base_lookup_by_pdevname() and syscon_base_lookup_by_phandle(), when implemented, do not return NULL, so none of the code using those function is written to check for that.

* PCI: imx6: Add proper i.MX6+ reset sequenceAndrey Smirnov2016-04-281-0/+1
| | | | | | | | | | | | | | | | | I.MX6+ version of the silicon exposed PCIe core's reset signal as a bit in one of the control registers. As a result using old, pre-i.MX6+, reset sequence on i.MX6+ leads to Barebox hanging during startup. Using exposed reset bit instead solves the problem. This commit is based on portions of commit c34068d48273e24d392d9a49a38be807954420ed in http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Acked-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | Some boards have to initialize the PMIC before other devices can be initialized. This requires three levels of initcalls: one level in which the PMIC is probed, one in which the board can call mc13xxx_get() and the third one to initialize the PMIC dependent devices. Allow to register a callback which is called once the PMIC is initialized. This way mc13xxx_get() is no longer necessary and the number of required initcalls levels is reduced to two.
