The OMAP36xx DPLL5, driving EHCI USB, can be subject to a long-term
frequency drift. The frequency drift magnitude depends on the VCO update
rate, which is inversely proportional to the PLL divider. The kernel
DPLL configuration code results in a high value for the divider, leading
to a long term drift high enough to cause USB transmission errors. In
the worst case the USB PHY's ULPI interface can stop responding,
breaking USB operation completely. This manifests itself on the
Beagleboard xM by the LAN9514 reporting 'Cannot enable port 2. Maybe the
cable is bad?' in the kernel log.
Errata sprz319 advisory 2.1 documents PLL values that minimize the
drift. Use them automatically when DPLL5 is used for USB operation,
which we detect based on the requested clock rate. The clock framework
will still compute the PLL parameters and resulting rate as usual, but
the PLL M and N values will then be overridden. This can result in the
effective clock rate being slightly different than the rate cached by
the clock framework, but won't cause any adverse effect to USB
operation.

The Kconfig currently controlling compilation of this code is:
arch/arm/mach-omap2/Kconfig:config SOC_DRA7XX
arch/arm/mach-omap2/Kconfig: bool "TI DRA7XX"
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tags etc. since all that information
is already contained at the top of the file in the comments.

Pull clk updates from Stephen Boyd:
"It's the usual big pile of driver updates and additions, but we do
have a couple core changes in here as well.
Core:
- CLK_IS_CRITICAL support has been added. This should allow drivers
to properly express that a certain clk should stay on even if their
prepare/enable count drops to 0 (and in turn the parents of these
clks should stay enabled).
- A clk registration API has been added, clk_hw_register(), and an OF
clk provider API has been added, of_clk_add_hw_provider(). These
APIs have been put in place to further split clk providers from clk
consumers, with the goal being to have clk providers never deal
with struct clk pointers at all. Conversion of provider drivers is
on going. clkdev has also gained support for registering clk_hw
pointers directly so we can convert drivers that don't use
devicetree.
New Drivers:
- Marvell ap806 and cp110 system controllers (with clks inside!)
- Hisilicon Hi3519 clock and reset controller
- Axis ARTPEC-6 clock controllers
- Oxford Semiconductor OXNAS clock controllers
- AXS10X I2S PLL
- Rockchip RK3399 clock and reset controller
Updates:
- MMC2 and UART2 clks on Samsung Exynos 3250, ACLK on Samsung Exynos
542x SoCs, and some more clk ID exporting for bus frequency scaling
- Proper BCM2835 PCM clk support and various other clks
- i.MX clk updates for i.MX6SX, i.MX7, and VF610
- Renesas updates for R-Car H3
- Tegra210 got updates for DisplayPort and HDMI 2.0

The OMAP Platform code provides possibility to select GP Timer as
default clocksource instead of counter_32K by using bootcmd parameter
'clocksource', but the system will crash during early boot when this
option is used on dra7 or omap5 platforms, because it will hit BUG()
statement:
omap2_gptimer_clocksource_init
->BUG_ON(res);
This happens because clk_dev alias "sys_clkin_ck" is not registered.
Hence, fix it by adding missing "sys_clkin_ck" clk_dev aliases
definitions for omap5 and dra7.

On dm814x we have 13 ADPLLs with 3 to 4 outputs on each. The

Note that for the clocks to work as device drivers for booting on
dm814x, this patch depends on "ARM: OMAP2+: Change core_initcall
levels to postcore_initcall" that has already been merged.
Also note that this patch does not implement clk_set_rate for the

Errata i810 states that DPLL controller can get stuck while transitioning
to a power saving state, while its M/N ratio is being re-programmed.
As a workaround, before re-programming the M/N ratio, SW has to ensure
the DPLL cannot start an idle state transition. SW can disable DPLL
idling by setting the DPLL AUTO_DPLL_MODE=0 or keeping a clock request
active by setting a dependent clock domain in SW_WKUP.
This errata impacts OMAP5 and DRA7 chips, so enable the errata for these.

The default clock enabling functions for TI clocks -
omap2_dflt_clk_enable() and omap2_dflt_clk_disable() perform a
NULL check for the enable_reg field of the clk_hw_omap structure.
This enable_reg field however is merely a combination of the index
of the master IP module, and the offset from the master IP module's
base address. A value of 0 is perfectly valid, and the current error
checking will fail in these cases. The issue was found when trying
to enable the iva2_ck clock on OMAP3 platforms.
So, switch the check to use IS_ERR. This correction is similar to the
logic used in commit c807dbedb5e5 ("clk: ti: fix ti_clk_get_reg_addr

Use the provider based method to get a clock's name so that we
can get rid of the clk member in struct clk_hw one day. Mostly
converted with the following coccinelle script.
@@
struct clk_hw *E;

-__clk_get_name(E->clk)

We're removing struct clk from the clk provider API, so switch
this code to using the clk_hw based provider APIs.

This code is never called with a basic clock type, so the check
here is not doing anything useful and is blocking the removal of
__clk_get_flags(). Remove the check so we can delete the
__clk_get_flags() API.
