b83db5b849 docs: dt: Group DT docs into relevant sub-sections 
The DT docs are currently all just lumped together in the doc build.
Let's organize the documents by kernel specifics, overlays and bindings.

As writing-schema.rst is about bindings, let's move it to the bindings
directory.

7248213cf4 docs: dt: Make 'Devicetree' wording more consistent 
There's a variety of ways 'Devicetree' has been written. This is most
evident in the documentation build contents where we have 'Device Tree',
'DeviceTree', etc. The DT spec has somewhat standardized on
'Devicetree', so let's use that.

b368d9e7c9 dt-bindings: ddr: Add optional manufacturer and revision ID to LPDDR3 
On some platforms, DDR parts are multi-sourced and the exact part number
used is not know to either kernel or firmware at build time. Firmware
can read identifying information from DDR mode registers at boot time
but needs a way to communicate this information to kernel and/or
userspace. This patch adds optional properties for this information to
the existing "jedec,lpddr3" device tree binding to be used for that
purpose.

b0c7459be0 x86/sgx: Wipe out EREMOVE from sgx_free_epc_page() 
EREMOVE takes a page and removes any association between that page and
an enclave. It must be run on a page before it can be added into another
enclave. Currently, EREMOVE is run as part of pages being freed into the
SGX page allocator. It is not expected to fail, as it would indicate a
use-after-free of EPC pages. Rather than add the page back to the pool
of available EPC pages, the kernel intentionally leaks the page to avoid
additional errors in the future.

However, KVM does not track how guest pages are used, which means that
SGX virtualization use of EREMOVE might fail. Specifically, it is
legitimate that EREMOVE returns SGX_CHILD_PRESENT for EPC assigned to
KVM guest, because KVM/kernel doesn't track SECS pages.

To allow SGX/KVM to introduce a more permissive EREMOVE helper and
to let the SGX virtualization code use the allocator directly, break
out the EREMOVE call from the SGX page allocator. Rename the original
sgx_free_epc_page() to sgx_encl_free_epc_page(), indicating that
it is used to free an EPC page assigned to a host enclave. Replace
sgx_free_epc_page() with sgx_encl_free_epc_page() in all call sites so
there's no functional change.

At the same time, improve the error message when EREMOVE fails, and
add documentation to explain to the user what that failure means and
to suggest to the user what to do when this bug happens in the case it
happens.
