Different hardware requires different configurations, but this distinction
was not made previously. Additionally, the error message was not clear
enough. Therefore, this patch will address the issues mentioned above.

The undervoltage flags reported by the RTC are useful to know if the
time and date are reliable after a reboot. Although the threshold VLOW1
indicates that the thermometer has been shutdown and time compensation
is off, it doesn't mean that the temperature readout is currently
impossible.
As the system is running, the RTC voltage is now fully established and
we can read the temperature.

This RTC has special 32bit registers which return multiple of the same
8bit registers at once. Use these to minimize register access. Also, do
the to/from BCD conversions right away, so 'tm' always contains values
as described in time.h.

The week register simply counts from 0 to 6 where the numbers do not

Currently, the Rockchip PCIe endpoint controller driver does not handle
the PERST# signal, which prevents detecting when link training should
actually be started or if the host resets the device. This however can
be supported using the controller reset_gpios property set as an input
GPIO for endpoint mode.
Modify the Rockchip PCI endpoint controller driver to get the reset_gpio
and its associated interrupt which is serviced using a threaded IRQ with
the function rockchip_pcie_ep_perst_irq_thread() as handler.
This handler function notifies a link down event corresponding to the RC
side asserting the PERST# signal using pci_epc_linkdown() when the gpio
is high. Once the gpio value goes down, corresponding to the RC
de-asserting the PERST# signal, link training is started. The polarity
of the gpio interrupt trigger is changed from high to low after the RC
asserted PERST#, and conversely changed from low to high after the RC
de-asserts PERST#.
Also, given that the host mode controller and the endpoint mode
controller use two different property names for the same PERST# signal
(ep_gpios property and reset_gpios property respectively), for clarity,
rename the ep_gpio field of struct rockchip_pcie to perst_gpio.

The Rockchip RK3399 TRM V1.3 Part2, Section 17.5.8.1.2, step 7,
describes the endpoint mode link training process clearly and states
that:
Insure link training completion and success by observing link_st field
in PCIe Client BASIC_STATUS1 register change to 2'b11. If both side
support PCIe Gen2 speed, re-train can be Initiated by asserting the
Retrain Link field in Link Control and Status Register. The software
should insure the BASIC_STATUS0[negotiated_speed] changes to "1", that
indicates re-train to Gen2 successfully.
This procedure is very similar to what is done for the root-port mode
in rockchip_pcie_host_init_port().
Implement this link training procedure for the endpoint mode as well.
Given that the RK3399 SoC does not have an interrupt signaling link
status changes, training is implemented as a delayed work which is
rescheduled until the link training completes or the endpoint controller
is stopped. The link training work is first scheduled in
rockchip_pcie_ep_start() when the endpoint function is started. Link
training completion is signaled to the function using pci_epc_linkup().
Accordingly, the linkup_notifier field of the Rockchip pci_epc_features
structure is changed to true.

Define the EPC operation ->stop() for the Rockchip endpoint driver with
the function rockchip_pcie_ep_stop(). This function disables link
training and the controller configuration, as the reverse to what
the start operation defined with rockchip_pcie_ep_start() does.

The function rockchip_pcie_init_port() enables link training for a
controller configured in EP mode. Enabling link training is again done
in rockchip_pcie_ep_probe() after that function executed
rockchip_pcie_init_port(). Enabling link training only needs to be done
once, and doing so at the probe stage before the controller is actually
started by the user serves no purpose.
Refactor this by removing the link training enablement from both
rockchip_pcie_init_port() and rockchip_pcie_ep_probe() and moving it to
the endpoint start operation defined with rockchip_pcie_ep_start().
Enabling the controller configuration using the PCIE_CLIENT_CONF_ENABLE
bit in the same PCIE_CLIENT_CONFIG register is also moved to
rockchip_pcie_ep_start() and both the controller configuration and link
training enable bits are set with a single call to
rockchip_pcie_write().
